Differential Temperature Measurement

SmartLine STT700 Temperature supports differential temperature measurements for dual input transmitters. When the loop current mode is set to "Differential" then the input range is from A to B for sensor 1 & 2 where


A = Sensor 1 Minimum - Sensor 2 Maximum

B = Sensor 1 Maximum - Sensor 2 Minimum



Digital Accuracy for differential temperature measurement

 If both input types are the same, then the digital accuracy equals 1.5 times the worst case accuracy for that input type.

 If the input types are different, then the digital accuracy equals the sum of the worst case sensor 1 and sensor 2 accuracies. For example, assume that input 1 is a J T/C and input 2 is an R T/C. Assume that the desired operating range is between 0 and +400 °C. The digital accuracy for a J T/C in this range is 0.30 °C and the digital accuracy for an R T/C in this range is 1.00 °C. Therefore, the worst case digital accuracy would be 1.30 °C.
