Main unit

Auxiliary unit


Main unit includes sensor and process connection, working principle as followed: 


The sensor module uses whole welded technology, in which has a compact overload diaphragm, a differential pressure sensor and a temperature sensor. The temperature is taken as a reference for temperature compensation. 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. 


NS---M3051DP Differential Pressure Transmitter is used for level, density, pressure and flow measurement of liquid, gas and steam. Then it will outputs 4mA~20mA DC HART signal and also it could be connected to RST375 hand communicator or RSM100 Modem to do the specification setting and process control.
