4. Function

PEX10: Pressure connection (intrinsically safe) with internal diaphragm (standard version).
PEX11: Pressure connection with flush diaphragm (intrinsically safe) for highly viscous or
solids entrained media which might clog the pressure port.
PEX10, PEX11: Pressure sensor(intrinsically safe), version with electrical connector or
flying leads.
PEX13, PEX14: Pressure sensor(intrinsically safe), field case version.
PEX15: Pressure sensor(intrinsically safe), highest pressure connection.
Function: The pressure prevailing within the application is transformed into a standardised
electrical signal through the deflection of the diaphragm, which acts on the sensor element
with the power supply fed to the pressure sensor. This electric signal changes in proportion to
the pressure and can be evaluated correspondingly.
