EGT amplifier (DSUB9)

EGT amplifier in a standard DB9 connector housing.
Compatible with any K-type thermocouple (not just VEMS EGT sensors)
Works from 10-15V supply, features 2 outputs:

• 1V / 100C output useful to watch EGT on a DVM: DVM shows 9.90 (V) for 990C EGT temperature. (Junction temp is considered, and no calibration is required.
• 0-5V output for dataloggers. 1V / 239 C
• Fahrenheit reading directly on DVM is currently not supported. If you insist on Fahrenheit-scale EGT reading (instead of the 0-5V output), that is you want 1000F=1.000V, write in the order note: not recommended: because there is an offset at roomtemp because 0C=32F not 0F. Effectively: 1000F=1.000V, 800F=0.794V, 1200F=1.206V)

A matching DSUB9 (male) connector is included.
Options:

• "with_wire=yes" means wires soldered (with a fuse) to make it easier to connect to +12V supply and DVM.
• A 6mm (conical type, see image) VEMS EGT-sensor (click here) is included if "with_sensor=yes"
