The interface circuit between typical pressure transmitter (such as the Dynisco company's 800 series of pressure transducer) and 1B31 is shown as the chart. 1B31 outputs stable +10 V excitation voltage, and the pressure transmitter full scale output voltage is 30mV. Seting 1B31 gain is 333.3 times could make the 0 to 10,000 lb / inch 2 pressure change into 0 ~ 10V output. For eliminating ground loops, signal returning side and shielded cables must be grounded in the same point. S is the calibration switch, and R is the branch calibration resistor, which can correct full scale output in 80%.
