The ME12 is a pressure transmitter with a ceramic measuring cell for over-pres-
sure and under-pressure and can be used for both relative and also absolute
pressure measurements. The pressure transmitter can be used with non-ag-
gressive liquid and gaseous media. Please see the technical data for the re-
spective measuring ranges.
NOTICE
Soiled or aggressive media
Please contact the manufacturer before using this unit with dirty or aggressive
media because the unit needs to be adapted for the specific customer in terms
of the parts that come into contact with the media.

2.4 Design and mode of operation
The pressure sensor work on the thick layer technology DMS principle. The
measured pressure acts directly onto a ceramic membrane that deforms when
under pressure. This changes the resistance of the attached DMS bridge. Elec-
tronics integrated into the device convert this bridge signal into an electronic
output signal.
Every pressure transmitter is programmed according to the code in the order
code on delivery. Also, the electrical connections can be used to configure the
pressure transmitter, adapting it ideally to suit the process conditions. You will
need a Transmitter PC Interface available as an accessory.
