CHT

Cylinder Head Temperature using a LJTick-InAmp. The LJTick-InAmp is a signal-conditioning module which provides two instrumentation amplifiers ideal for low-level signals such as thermocouples. Each amplifier converts a differential input to single-ended. The LJTIA has switches to choose from 5 gain settings (x1, x11, x51, x201, or custom) and two output voltage offsets. The 4-pin design plugs into the standard AIN/AIN/GND/VS screw terminal block found on newer LabJacks such as the U3 and UE9.

Trying the above with a Type-J CHT sparkplug thermocouple which outputs 9.81 mv @ 400f.
