4.1 Short description
The prevailing pressure is measured at the sensor element through the deformation of a diaphragm. By supplying
power, this deformation of the diaphragm is converted into an electrical signal. The output signal from the pressure
transmitter is amplied and standardised. The output signal is proportional to the measured pressure.
4.2 Scope of delivery
Fully mounted pressure transmitter
In order to protect the diaphragms of ush process connections, they are provided with a special protection cap.
