Foxboro AA22ID1MGDAFJB1A DP Transmitter

Feature & Principle

It is Foxboro intelligent differential pressure transmitter. It uses capacitance sensing principle to detect the pressure difference between high pressure side and low pressure side, converts the tiny capacitance variation signal into standard 4-20mA+HART digital signal. It supports square root output for orifice flow measurement, built-in continuous self-diagnosis, overpressure protection function, can realize remote parameter configuration, zero calibration and fault query through HART hand communicator. It has good anti-interference and long-term stability, widely used for closed tank liquid level, pipeline differential pressure and flow monitoring.
