4. Function
2-wire Two connection lines are intended for the voltage supply.
The supply current is the measurement signal.
3-wire Two connection lines are intended for the voltage supply.
One connection line is intended for the measurement signal.
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 evaluated correspondingly.
