PS-20: Pressure connection with internal diaphragm(standard version).
PS-21: Pressure connection with flush diaphragm for highly viscous or solids entrained media which might
clog the pressure port.
Function
The pressure prevailing within the application is transformed into a sensor signal through the deflection of
the diaphragm, which acts on the sensor element with the power supply fed to the transmitter. This electric
signal changes in proportion to the pressure. The electrical signal on the switching output is changed when
reaching the preset switching point.
