4. Function

The pressure transmitter is available in 2 versions:
1)Pressure connection with internal diaphragm(standard version).
2)Pressure connection with flush diaphragm for highly viscous, dirty or solids entrained media
which might clog the pressure port.
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 transmitter. This electric signal changes in proportion to the pressure and can be evalu-
ated correspondingly.
