Thread: Does this look like the right stuff? (EGT)

Good to see they have blue now. I had the red one in my last discovery and the light was too aggressive at night. Though it seems these new models have a dimming function which the old ones didn't.

Looks the same as I have (except for the blue)

Does anyone know where I can get the K type thermocouple probe which is long enough for the 300tdi EGR blanking plate spot?
I think soemone said it needs to be in excess of 45mm to get in the gas stream...

So I'm guessing that the one I put up is wrong then?
as thats where mine will be going.

here is a link to the K-type

Temp Sensors, Thermocouple : auberins.com, Temperature control solutions for home and industry

So is this correct what brian says? am I looking at the wrong one?

Hi DB.
I've got the original P/N that you posted, the weld-in one (you've probably already seen the tutorial I did on it).

Since then I've read other posts - as Brian is referring to - that suggest its not long enough to reach the gas stream.
I haven't had a chance to look into it further as I've been overseas for work and busy dropping the auto out of my disco once I got back.

Your post prompted me to email Auberins to see whether they can do a straight probe the same diameter/spec as the weld-in one.

I'm pretty sure that the weld-in one will have started life straight and then been bent.

If you want to hold off a day or so before ordering I should have a response from them.

ok mate thanks will do......however I was looking at the one that could be tapped in, is the weld in one better? I think tapping it in would be easier...also means when the car goes you can remove it easily and just put a small bolt in there...I'm guessing

Oh and yes it was your tutorial that prompted me to look at there site and ask the question......however I couldn't remember at the time who did it when I was searching for the stuff

From what I can work out from the website, the weld-in, tapped, and clamp on versions all use the same thermocouple (3/16" diameter, exposed tip, temp range etc), so their response should apply to the tap-in one also.

I haven't found any others on the site that are the same - the long ones seem to be thinner diameter (4mm IIRC).

Just for the record, I've found my current setup to be very responsive - it doesn't react like its sitting in a pocket of low temp gas, and to be honest I'm not 100% sure that a longer probe is necessary (although I understand the reason why it could be). Even the probe on the Thermoguard site appears as though it would only have about the same protrusion as my current one.
What I would really like to do is to run the 2 probes with different lengths side by side in the blanking plate, and see if there is a real difference in what they sense.
