Functional principle
The pressure transmitters of the PT…-1 series
operate with piezo-resistive ceramic measuring
cells. The ceramic diaphragm is unbalanced
in proportion to the pressure applied.
Depending on the sensor type used, the processed
signal is provided as an analog output
signal 4…20mA (2-wire) or 0…10V (3-wire).
