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).
