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.

4. 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 evaluated correspondingly.

5. For your safety

„ Select the appropriate pressure transmitter with regard to scale range,
!
performance and specific measurement conditions prior to installing and
starting the instrument.
Warning
Observe the relevant national regulations and observe the applicable stan-
„
dards and directives for special applications (e.g. with dangerous media
such as acetylene, flammable gases or liquids and toxic gases or liquids and
with refrigeration plants or compressors). If you do not observe the appro-
priate regulations, serious injuries and/or damage can occur!
