詳 細 | ||||||||||||||||||||||||
The differential pressure transmitter has a ceramic differential pressure sensor with thick film technology, which works according to the principle of a Wheatstone bridge. The differential pressure deflects the ceramic diaphragm, thereby changing the strain gauge signal, which is amplified to a standard current output signal by the integrated electronics.The sensor is mounted between the two case halves and sealed by o-rings. The sensor is electrically connected by means of a 3-wire cable which is led to the room for service connections through a protective plastic tube.The differential pressure transmitter has two lugs for mounting. | ||||||||||||||||||||||||
