A kind of typical pressure transmitter with 1 b31 interface circuit as shown in the figure below. 1 b31 stable output of + 10 v excitation voltage, pressure transmitter full scale output voltage is 30 mv. Set 1 b31 gain of 3333 times, can make the 0 ~ 10000 pounds in 2 pressure into 0 ~ 10 v output. To eliminate the grounding circulation, signal back end and shielded cable must be in the same point grounding. S for calibration switch, R calibration for the branch resistance, can the full output 80% calibration point.
