Thermocouple/EGT Sensor

[skippydiesel]

One of my two EGTs has become slower than the other to indicate (from cold)  and remains consistently lower, during all phases of operation.  Its not by much but is irritating.

 

Before you respond with advise about carburettor balance, exhaust blockage, electrical connection integrity, swopping leads/positions. etc - all of this has been checked/double checked - the difference remains.

 

It seems to me that the thermocouples are not equal in their reaction to EG temperature - one or both should be replaced.

 

If possible I would like to determine which EGT sensor is reading high or low - Anyone got a test for this?😈

This has K thermocouple temperature/voltage tables. You may be able to check at ambient with a good voltmeter:

Thanks for that IBob.

 

I belatedly Googled for this information and got quite a few ideas - bit less technical (as befits the asker) than your excellent 😈
