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).
