The complete measuring system consists of
•
Cerabar S pressure transmitter with 4…20 mA signal output
•
optional four-character pressure display
•
power supply 11.5…45 V DC
For electronic versions with HART protocol, a digital communication signal is
superimposed on the signal current and is used for remote calibration.
These instruments have additional functions also to measure level.
