Introduction of Differential Pressure Transmitter
The differential pressure transmitter module uses whole welded technology, in which has a compact overload diaphragm, the positive end of the differential pressure sensor is connected with high pressure chamber of sensor capsule; The negative end is connected with low pressure chamber of sensor capsule. Through the isolated diaphragm and filling liquid, the differential pressure is transmitted to silicon die in the inner of differential pressure sensor, which makes the resistor of sensor die change. So the detection system outputs different voltage. The output voltage is in proportion to the pressure variation, and then it is transmitted to standard output by adapter and amplifier.
