Differential quasi-static temperature monitoring
PROCESSING MODES AND APPLICATIONS
7.16Differential quasi-static temperature monitoring
This type of processing is equivalent to that used for differential housing expansion
processing. See 7.11 Differential housing expansion.
In this situation, two temperature probes are used and the MPC4 is set up for dual-channel
processing. The differential output is given by:
ΔX = X1 X2
X1 input
