Perchased a K type egt probe but i didnt know how to connect it to my datalogit or my LM-1 wideband to give a range of 0-5v.
So had a friend of mine who is a whiz with electronics to have a look.
Short of it is hes managed to make a small (1in x 2in) board that will give out a 0 to 5v signal and wont ever give out a negative signal or anything higher than 5v.
The temp range is 500f at 1v and about 1600f at 4v.
We are looking if there is a market somehting like this as thats what he duz for a living.

Anyone interested just let me know via this thread.

Think the pricing will be about £45 GBP

Any techy questions can be answerd via charli himself, i will post his email if enugh people are interested.

Oh and the board has all relevent wires on a flex about 2ft long and also has 2 little screw connectors to attach your EGT wires, all that is required is connect it to your datalogit.

The temperature range needs to be wider (higher). At least to 2000F.

He can programme the thermo thingy to whatever is required.

I mentioned that some guys who are track tuned go upto 1800 and above and he replyed that it would not be a problem.

Just let me know the ranges for 0 and 5 and he will make it.

Basicly all you do is connect this to your egt and datalogit then conect a 12v and grnd and thats it.

Same thing but thermo thingy included also no matter what the temp ranges are it has safty devices attached so as not to go negative v or above 5v, i have been told these ranges can harm our datalogits and wideband loggers.

Reitterate its kinda the same but a lot more as well.

I will soon be reciveing all the info as im a numpty when it come to electonics, will post it as soon as i do.


^^^ ended up posting this reply in the wrong thread :\ ^^^^^

Thermocouple Interface.

- K type thermocouple.
- Cold junction compensated.
- Supply 7 to 17 Volts DC.
- Output approximately 200'C (360'F) per Volt. Calibration data supplied with each interface.
- Range: Linear output from 0'C (32'F) to 870'C (1600'F) followed by a non-linear output up to 5 Volts at approximately 1000'C (1800'F) (rember this can be preprogrammed to anything)
- Output limited to 5.1 Volts.
- Connections: Two screw terminals for thermocouple; Two supply wires (0 & 12 Volts); Two output wires (Signal & Signal ground)
- Size approximately 50x25x12mm (2"x1"x1/2")
- Weight approximately 50 g (2 oz)
