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 sensors with regard to scale range, perfor-
!
mance and specific measurement conditions prior to installing and starting
the instrument.
Warning
Observe the relevant national regulations (e.g.: EN 50178) and observe the
applicable standards 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 appropriate regulations, serious injuries and/or damage can
occur!
