Thermocouple Type A or B

[Robzki]

Hi all

 

I'm in the process of sorting my egt gauge. I am trying to buy a probe and the harness to fit the plx module. I have the choice of type A or B when I buy the harness, is it just the plug that is different. If so which is the most common?

 

I have read that inconel would be the best choice for probe?

 

Thanks

inconel type a and b mean nothing.

 

you need type K thermocouple. some connection plugs and some compensation cable..

 

buy all from rs components.

There is a chap on ebay selling this stuff off silly cheap. "phil.jone5" is his user name. I bought 5 K types of the 3mm @ £8 each + £2 for the brass gland clamp fittings.

thanks. what I meant to say was when I buy the harness I have a chice of A or B to fit a k-type thermocouple. if that makes sense. I can only buy the harness from plx devices.

Hmmm long probe at 4" and as you say lyndon, its ridiculously cheap.

 

Anyone have any views on this?

I would never, ever use anything but an Inconel probe if used before the turbo on a high output petrol engine. Putting the probe after the turbo is pretty pointless. I also use stainless glands as they are more likely to come undone in a years time if I want to renew the probe or alter something. 99% of gauges are configured for K type probes.
