Hello all, thanks in advance for any help y'all can give.
I'm running a 645-16 turbo in a marine application. We've been trying to figure out exactly what kind of thermocouples this unit uses and none of my manuals are any help besides a part number. I have a panel mounted electronic reader that is adjustable for multiple types of junction but none seem to reflect a realistic exhaust temp.
The type K junction setting is the most accurate while the engine is stopped (with jacket water preheat both on & off) but under full load at around 900 rpm they show around 1100f which seems ridiculous since the infared gun shows about 600f on the manifold.
So does anyone here know what type junction they are or if there should be supplimental resistors or something similar in the circuit?
The pyrometers we are using are EMD part# 9310243.
Thanks again for any help.
