1. The resistance bridge on the left of the dashed is sensor's bridge circuit;
2.The sensor has no laser trimming board, it compensates zero and temperature drift by outer compensated resistors, the connection to see the above chart; connect zero trimming resistor R3(R4), the other R4(R3) is short circuit as negative power supply; R1 or R2 is zero temperature drift compensated resistor, only one of them is used, the other is open circuit, please select the right resistor according to the specification label enclosed with sensor; R5 is sensitivity temperature compensated resistor. We suggest that please connect the outer resistor and differential pressure sensor as close as possible.
