2.4.2.1 Exhaust Gas Temperature (EGT) Probe

The TP-EGT-1 exhaust gas temperature probe may be used to measure temperatures other
than exhaust gas temperatures; however, the TP-EGT-1 exhaust gas temperature probe is the
only TMP100 temperature probe that has sufficient range to measure exhaust gas
temperature.
NOTE
You may connect TP-EGT-1 exhaust gas temperature probes only to the
terminal pairs T0+/T0- (pins 1 and 2) or T1+/T1- (pins 3 and 4).
Please refer to Figure 3 for connecting the TMP100 to a TP-EGT-1 exhaust gas temperature
probe. Please be sure to connect the red wire from the EGT probe to the negative "-" terminal,
and the yellow wire from the EGT probe to the positive "+" terminal. This figure shows the
connection of the exhaust gas temperature probe temperature to channel 0 via the terminals
named T0+ and T0-. Connection to channel 1 is similar.

2.4.2.1.1 Cable Extension

If the cable on the EGT probe is not long enough to reach from the probe location back to the
terminals on the TMP100, you may extend the cable using only K-Type thermocouple
extension wire. Other types of extension wire will result in inaccurate temperature readings.
