Clark Solutions 652 Series Differential Pressure Transmitter

The differential pressure transmitter series 652 are especially suited for the continuous level or flow monitoring of neutral and slightly aggressive liquids and gases in heating, ventilation and process applications. The pressure or differential pressure to be monitored acts on a diaphragm, which in turn acts against a spring. A permanent magnet fastened on the diaphragm moves in the direction of a hall sensor mounted outside the pressure case. This sensor emits an electrical signal which is proportional to the magnetic field. The signal is linearized, compensated and amplified
