View Full Version : Ian S charge temp gauge; a new batch...
Hi all,
Over the last couple of years people have asked me if I still have any of those charge temp gauges that I used to make. I didn't have any but I am now about to make another 10 units.
So if any of those people who asked still want one, please let me know.
Or, of course, if you didn't already enquire, then feel free to do so.
There is now more choice on the display as Trumeter have developed negative backlit in more colours and RS components are stocking the new and wider range.
Here the list of RS part numbers:
Go to http://uk.rs-online.com (http://uk.rs-online.com/) and enter these part numbers one at a time into the search box. Note, there are two sizes listed there of most types, each with it's own number:
(48mm x 24mm with with 10mm character height)
337-7224
337-7189
553-642
553-759
553-804
553-775
(72mm x 36mm with 14mm character height)
337-7246
553-646
657-2006
553-636
657-2012
What used to be my standard size was 48mm x 24mm with with 10mm character height and the green back light. The larger ones are 72mm x 36mm with 14mm character height.
I used the small size display as it would fit neatly into the fascia somewhere but I did find it too small to read when at full torque / power on narrow roads.
If you're wondering where the blue ones are, small blue ones are not currently available and the larger blue ones are only direct from the manufacturer in numbers greater than 5. I might be able to buy mixed types from withm with a few blue ones. Unfortunately, there are no amber ones, they were not manufactured.
You can chose a display from that RS list if you like and I can then buy and use that.
I can't tell how well lit / visible the text in negative backlit ones will be. Good at night I'd guess, probably better than a 'normal' type. But daytime, maybe a bit less visible.
The total price per charge temp unit I've not finally established yet, but it probably won't be too far from what it was at about £130.
Thanks,
Ian
Always seen quite a few people who have these. can you stick my name down for one :)
What sort of fitment is required for these, noticed that some people just put it in one section of the carb top, however running F7P turbo would it just need securing in place or does it need a tube to be fitted into?
I can happily vouch that these gauges are the don.
Ian kindly made me a 2-gauge setup (act & egt) for my old Raider, and it was spot on - Superquick sampling rate, nicely made, robust, and easily worth the money.
It's fair to say Ian knows a thing or 2 about electronics, so if you have any concerns over his workmanship/what these gauges will be like, you really don't need to have.
And as proof of that, Ian, if you can make me a 2-gauge setup again, you can add my name to the group buy list for starters please.

Sorry about the awful sound track. The camera sound recording is duff.
This unit, with the fine wire thermocouple, will go to, and dwon from, 250°C in about the same time.
250 is the max rated for the fine wire, or the sheath melts!
I have just received the EGT probe and perhaps I could repeat that vid with that, but although it's possibly the fastest EGT probe in town it's still a lot slower than the fine wire, but does go up to 1200°C. The main problem I have is that I can't get the water to say in the can at that temp.

What sort of fitment is required for these, noticed that some people just put it in one section of the carb top, however running F7P turbo would it just need securing in place or does it need a tube to be fitted into?
I've uploaded some photos here: http://www.rtoc.org/boards/album.php?albumid=789
I fit the fine wire probe into a 4mm OD somewhat flexible tube then that goes into a quick release fitting. This allow for a little rotational movement and for the probe to be removed easily during engine or carb servicing / adjusting / modifying / removal, avoiding the swift destruction we've seen with other vendors mounting methods.
The fine wire does need some support inside the boost pipe as it would just get blown flat against the pipe side.
From my instructions:
"You can push the tube into the carb top up to the black band of glue lined heat shrink. This should mean the tip is in the middle of the carb top, ie, half way across the air flow. We found that having it right by the side gave erratic readings, when water inj was in use at least. It seems to work OK less than half way in, just not right at the side."
Ian, Ricardo fitted one of your last ones to my current car.
I will get some pics up of the fittings and the probe itself, after my cup of tea of course :coffee:

Ian, does this set up use a power converter/voltage regulator type deal to covert the 12-14v car supply to 5v supply? I'm assuming it uses a 5v circuit?
The reason I ask, is that I would like a 5v converter/regulator to power up my 3 BAR MAP sensor for data logging.

Hi yes, that's what this does:
http://i87.photobucket.com/albums/k122/Dr_Toor/Car%20stuff/SDC10006.jpg
+12 in, +5v out. Reverse polarity protected. Fuse protected. Input over voltage protected to about 60V. Needs an earth connection.
Also can have an adjustable out from about +1.25 to about +9 or a bit more (ie, about 3V less than supply, so 11V for 14V supply). I have to use an adjustable for the blue back lights as they need more than +5V.
The regulator is a 1 Amp, however, the heat dissipation of the box is intended for less than 200mA at about an 8 volt drop, ie, +5V. More current = more heat. Higher voltage drop = more heat. And in Britain too, so higher ambient = greater heat dissipation needed. Easily remedied with a larger or maybe a vaned box.
will you be able to post one to Cyprus for me?
I think so. But not with Parcel force, they require about £50!!
I had a look at parcel to go but didn't get very far, Seems that one of the couriers does deliver to Cyprus, maybe FedEx. DHL indicated they don't include Cyprus.
I seem to think that the packaged CT gauge weighs between 500g and 1 Kg. Do you have a courier that you prefer to use? Can you find a price?

Thanks for the kind words / recommendation :)
Thanks to everyone else for your interest in this product. :)
Last week, due to a one day price reduction by the supplier, I went ahead and bought enough amplifier chips to make 10 single gauges or 5 duals.
Since then, there have been a few more requests for duals and singles so it looks like I'll need to buy a few more but at a somewhat higher price. I could order another 10 chips and make the price break again if I have some payment up front to confirm the interest.
Due to the interest in dual gauges, and the difficulty I had in doing the last two duals, I've spent the last week looking at ways and sourcing suitable parts to make them more practical to manufacture without increasing the final price. I've made some progress.
On Monday I plan to be placing orders for most of the rest of the parts for a somewhat larger sized batch of gauges than I'd originally considered.
What I need really, is for you all who are definitely interested to send me a deposit to cover the cost of buying the displays from Trumeter, rather than RS, as this gets a discount and allows me to keep the final price down by a few more pounds. It also means that I will sell what I've bought and not have a £ few hundred in parts sitting here for a couple of years.
After this group buy of gauges, I'll still be able to buy more as needed but at a higher price which I'll have to reflect in the final price.
£30 per display will be fine. So £60 for a dual.
I can accept either PayPal, but please pay the fee yourself, or direct bank transfer.
I'll pm the payment details.
I'll be aiming to deliver with a couple of weeks.
Thanks.

I can vouch too. Awesome bit of Kit!! Ian can the egt be retro fitted to the afr single gauge type that i have??
so whats the sampling rate? how many times a second does it take a reading?
I know of a place that does the exact same thing ACT version and EGT version available looks exactly the same and they both sample at 3 times a second

You can plug in an EGT probe as it is and should give you the full range, up to 1200°C.
But no your unit can't be turned into a dual with an extra display added as it requires:
a different circuit board with the extra chip,
an extra signal wire and earth in the loom to the displays,
an extra display to be wired into the loom,
an extra K-type socket of a different type fitted into the black box, and there isn't room to do so without removing the existing one, cutting a larger hole for two of the other type, moving one of the cable glands around to the side, meaning all the internal wiring would have to be re-made.
http://www.randbmotorsport.co.uk/shop/Details.asp?ProductID=450
That's the improved version of the rubbish one they had out some years ago.
The DISPLAY looks the same because the display IS the same panel voltmeter from Trumeter.
But that's about where the similarity stops.
The reliability of their old one was very poor because the production methods used were very cheap indeed and very poorly executed. I knew two people with one of their gauges and the probes kept snapping off at the carb top, then then backlights stopped working and then all the hot glue melted and ran out from behind the display where they'd fitted the baking hot regulator UNHEATSINKED which was doing all the damage. After a while the regulators failed too and both of those people bought one of mine.
Using a k-type thermocouple, the AD595 amplifier chip needs to be kept cool as it does not read accurately in an ambient of 50°C or more which is why I've gone to such lengths to keep it cool and also to make the whole thing as reliable as I can.
My 2nd prototype had the chip and regulator in the same metal heat sink box, which in the summer went to about 60°C. So no good then. Hence two boxes, more labour, higher costs.
Also he appears to only offer blue, and for me, about 7 in 10 people have requested not blue. Also does not appear to offer a dual.
The parts cost of mine is higher than the sale price of his. And that's with me buying as cheap as I can, all be it for small quantities.
I think Trumeter always did supply a pre-made display and AD595 but it was too large to neatly fit in the fascia and quite expensive too and still needed as separate PSU to be made and some means of reliably joining the wires. Also, although having the integrated AD595 would be a lot cheaper as that is an expensive chip to buy here in the UK, I wan't happy with the AD595 being on the back of the display as the displays are often mounted up high in a black box in the direct sun which in the summer in a hot car would probably take it over the 50°C.
That's why I ended up with the one I'm offering now.
I also thought it would be a good idea to measure to minus °C to indicate a possible carb freeze so I used a DC to DC converted to generate a negative voltage. I doubt the Rainbird one does that. I'd guess he still does not use rugedised electrolytic capacitors either that are reliable for many years in low temperatures and where condensation may be an issue and don't drop their capacitance as temperature varies. To get the full range of 1200°C I use a second DC to DC converter in series with the first one. Whilst that seems hot, there was a 5GTT in this club that was showing 1100°C (which may have been the limit of his gauge so it could have been higher), faulty maybe, but that's the whole point of diagnostic equipment. The Rainbird one would have topped out before then.
So, mine also measures to minus °C , +1200°C, has a dimmer control, a switch to toggle to ambient temperature and the new ones should have a feature that auto dims when the car lights are switched on, I think this might be needed for the -ve backlit displays. And a choice of display colours and sizes. The carb top fitting I devised has four years in service and has been 100% reliable and we know how often the carb tops are taken off with 5GTT's, especially some of them!
Of course, if all the manufacturing and all the parts for mine were sourced and assembled in Malaysia (where Trumeter have their display made) the total price would be a lot less.
I'm not making a living at making these units. I'm only doing this batch now as a few people had had a look around the internet and not liked what they found and asked me if I could do something.

screen refresh isn't the same thing as response time, Ian's circuit doesn't sample, it's analogue, only the display does that. 3Hz is pretty standard for a display, how fast can you read? But the point is, how fast does it respond to a step change in temperature? Ian shows this on his clip.
Ian ,could you make one with long enough wiring to get to the back of the GTA please ?
It also needs to fit the GTA inlet plenum ..it can go into one of these two connections ?
It would be parallel to flow ?

cheers mate
could you make one with long enough wiring to get to the back of the GTA please?yes that's just me asking Labfacility or Universal to supply a longer fine wire thermocouple next week with the rest of the order next week. Can you have a measure and tell me how long you need? We can order it longer and you can just cut it down at the plug end and re-terminate if you want to. I think there very little extra cost in ordering an extra meter or three. There is a limit to the length before resistance becomes a factor, I think we're OK with a few meters but I'll check.
It also needs to fit the GTA inlet plenum ..it can go into one of these two connections ?
It would be parallel to flow ?I can't really make out where you mean on that photo. But it should read OK if it's somewhere in air stream, I think parallel to flow would work, but as the tip would be in a leeward position after the tube there might be vapour condensate deposit on the tip which could cause erratic readings. The 4mm tube I use as a jacket has ony been tested at about 25mm into the airstream. It's pretty stiff at that length but if you need to poke it in further to get past any swirling or dampness near the sides and reach an area of smooth movement then it should remain stiff enough and not get bent over by the pressure. Can it go in from another direction?
I've just had a nose at your pics ....The thermocouple goes to the box of tricks and then it's just std wiring to the display ? yes ?The box of tricks can mount near the ecu .
I would need about 1.5m to get from the plenum to inside the rear of the car then its about 3.5m to get up to the dash .

You're correct, but alas, as far as I know, Trumeter don't do a display with two lines of text.
I looked at other makes and the only ones I found at the time had very small characters and were not backlit.
I can vouch for these as I had one, super fast & accurate, I thing Ricardo had mine, or was it Logg... ??
I bought mine directly off the main man, and yes they are probably the best piece of kit to buy and fit.

Any news on gauges Ian?:confused:
Hi, no need for concern, I now own about 12 gauges worth of components.
I couldn't just crack on with them as the new displays have different resistor values not just to eachother but to the old ones I used to use so the paradigm I hitherto used for construction has to be re-jigged a bit. It's not a big deal, just takes a bit of testing and measurement and then some more testing and measurement.
Then I've been distracted a bit over the last couple or so weeks by other issues that took my attention away from the CT gauges.
The exposed tip fine wire thermocouples which are being made for me by Labfacility won't be done until early to mid Jan and I'll be hoping to be able to post the gauges out then.
Have a happy Christmas :ho:

Are gauges almost done ian, the summers coming;)
Not yet auto dimming circuit.
The first version would not work with blue displays simply because they are so critical with voltage, ie, almost no change takes them from off to full on, and they need a high voltage and there is no more voltage overhead available as I'm already running them at +7V, the maximum the rest of the display can take and they most of that for full brightness.
Just the 0.7V dropping across the circuits series diode proved to be too much and made them too dim. Would probably be fine if I could use +8 Volts. But I can't. The regulator needs a few volts above the output voltage and some of the wiring behind the dash in the 5GTT can be less than 10V with the heater fan on.
So, version two is on paper and needs to be built and tested.
I could make them up and send them out as they are, but if I can make this feature work, some of them at least will be better for it.
newbstar*
03-04-2010, 11:20
So how are you going to get around this problem?Different displays or fiddling with the circuit, diodes ????
Plan to use a BD139 after the LEDs. The drop across that might be 0.2V.
Then to dim the LEDs shunt it's base with a 5551 with a pot in the emitter.
Or maybe put the pot in the base of the 5551.
Just an update. I managed to build up and test various configurations of the circuit together with a blue display last Sunday. Pressed on until 3.30am by which time it all seemed to be working nicely.
Just need to warm it all up with the hot air gun to check there is no significant current increase with the thermal increase that will occur in a car in the summer.
Thanks for your patience.
Good stuff .

how we getting on ian.
Wow, another month has already vaporised :crap: Where did that go? :confused:
Anyway, I hoped to have some out by the end of this week but I had to draw another 9 month long project to a close in the last 8 days, completed today.
Much of the Charge Temp work is done. Two more boards to populate, then the plastic boxes to mark and hole, looms to make and then join the parts to those.
Here are some progress photos...
Loving this thread... Quality use of the variboard :D,
Might be worth getting hold of a retro etching bath and making a batch of pcb that way on the next run? Save a load of time.
Keep up the good work :agree:
Thanks :D
It certainly would be a lot quicker to populate the boards if they were PCBs.
To make just 12 or so myself though it becomes less worthwhile once all the PCB cutting and drilling is done. There'd be up to 65 holes per board, and I'd have to find someone to make the transparency.
I'd also have to get myself some new layout designing software and figure out how to use it. My existing one, Ares from LabCentre, which I've not used for maybe 10 years, was made for Win95 / 98 and wouldn't work with XP.
If I was to do quite a lot more of these, which is unlikely, I'd get the boards made. Last time it cost me about £5 each for 30 similar sized PCBs. Maybe that would be £10 now which is therefore £10 extra to the bill of materials per unit which is already very high.
Another progress report..
The looms are made and fitted to the plastic boxes.
I'm now adding the boards and regulators to the boxes and joining on the K-type plugs to the leads. It's taking a painstaking 2 1/4 hours each unit. I did two yesterday and one today. I was hoping to do 6 each day :( .
Right due to problems in life I am having to leave the renault scene, as I was one of the few and very lucky members to put my name down and actually secure one of these gauges I am now going to have to sell it before I have even received the item or even before its built:cry:
If anyone is interested please pm me and we can have a chat. Don`t miss out on one of these gauges. Just wished I had a renault 2 use it on:dearme:

No. But I'm getting there :)
4 posted out of 6 complete.
Should have 2 more ready over the next few days and if payments are in by Monday they should be posted.
That leaves from the original order the two dual green's of you Mart and MFaulks and the dual white for Big Jim.
Since then I had another. I think that leaves just 3 sets more of components.
The two green duals are done but for the displays and therein lies a story of frustration. After trying to buy these displays since December and being told repeatedly "in a few weeks" now I'm told Trumeter 2 weeks ago went into liquidation and never actually had thoses parts or supplied them to the distributors. :dearme: :denied:
So, someone who works there had a stock check and found 45 small green ones like Mart you wanted, they were there all the time but under a bit of paper or something, just as well they'd gone 'missing' really or they have been sold already, I tried to buy some of those today but they've discontinued credit card payment ( :crap: ) and I have to pay by BACS, OK fine, no, they have to send me a pro-former first to which I have to respond, blah, blah. It didn't show up :sad2: I already got an email two days ago in response to my purchase request that followed my two phone calls. That wasn't good enough :crap: :sad2: . I tried to simply reserve them pending payment, no they won't do that. :mad: :rant: :smashpc: :sad: :smokin: :coffee: :)
Anyway, hopefully they'll be mine on Monday, then yours :)
Got mine this morning :cool:
All looks very good and the instructions very detailed :agree:
Although all the locations are for a 5 gtt :rolleyes::D:p;) I'm sure I'll work it out .
Thanks Ian .

Arrived today, good instructions and packaging.:agree:
From first looks is a surperb kit, need to have a read and try and find a place to put it in :) top work there :agree:
Anyway, hopefully they'll be mine on Monday, then yours :)
Any joy?
I'm starting to feel left out :cry: :D
Got mine yesterday Ian, really pleased with it. Build quality is awesome :agree:
Thanks everyone for your very good feedback. :)
Any joy?Yes, the rest of the displays arrived this morning :)
Didn't want to raise expectations by saying they were on their way or anything in case there were further delays. They had lost the ones they previously found that I'd bought. But luckily, they evidently found a few more.
Hi Ian,
I don't suppose you have any of these left over clogging up cupboard space? :)
Hi Jack,
Yes I do have three in stock.
All with the smaller green back lit display. All single probe only.
I won't be able to do a dual one though. I'm not currently making them. These are from the last batch.
Great, could you send me a Pm with the details on cost etc please.

Ian, can you supply the EGT probe or does CPC sell it?

Have you ordered one of the cheap ones off ebay?
Ian, can you supply the EGT probe or does CPC sell it?Hi Matt,
Yes I can. I buy them from Universal Thermosensors. One EGT Probe and one stainless steel compression gland costs me about £52inc VAT + UTs £11.75 postage fee.
http://www.rtoc.org/boards/picture.php?albumid=789&pictureid=11917
I have them made with the Hastelloy sheath about 500mm long, so the 250°C parts, ie the potted seal, can be cable tied well away from the exhaust side. The stainless over-braided extension cable is about 2 metres.
RS sell some cheaper ones that might do for a while. Also 1.5mm diameter stainless steel sheathed, but a cheaper steel, the UT ones are Hastelloy X. They have a plug, as above photo, attached direct to a short, maybe 6 inches, probe so you need to get a socket and a K-type extension cable and another plug. I seems to recall they do some slightly longer versions too. The plug / socket is not ingress proof so will get water in it and, over time, dirt. But the metals, Alumel and Chromel, don't really corrode, if at all, so should be OK. The plug / socket is only rated for something like 250°C so near to the exhaust in the particularly hot 5GTT could see it melt.
I don't now know if CPC sell something suitable. I had a quick look and it appears they don't.

Thanks Ian, great info that! Eventually I'm going to need one and was thinking of sharing my CT module when needed as long as no further calibration is required?
sharing my CT module as long as no further calibration is required?Should be fine. I just checked my records and your version is listed as capable of reading up to 1200°C.
I can't vouch for the accuracy at that though as I didn't test the EG temperature performance back then like I did with the recent ones, at 800°C.
It'll probably give you a near enough idea I should think. Within ±50°C maybe. To trim it you could get a calibrated k-type meter / multimeter and a paint stripper gun and heat the tip up on your probe until it glows. Read the temperature and then plug it into your 'in-car' gauge and repeat the test. You need to be very consistent with the probe position in the air gun air stream. Just 1mm side to side can be 100°C different.

Cheers for the pix ian. Yeah ordered a cheapo one off the bay, didnt realise more of these proper ones were being made:rolleyes:
The ebay one has a small single probe for a sensor though. It will probably be pants I may try an ian s one at the same time to see how far out it is:laugh:
didnt realise more of these proper ones were being madeThey're not. I have two left from the last batch. A green back lit display and a blue one.
