Praxistipusingtheexampleofthe”connectionofapressuretransmitter-1..7bar”:
Here the indication on the pressure transmitter is clear (-> -1 bar) relative to the ambient pressure The
adjustment of the pressure transmitter in the controller is carried out using absolute pressure values (the
absolute pressure cannot be negative). In order to parameterise the above pressure transmitter with the relative
pressure indication - 1 bar (at 4 mA, i.e. 0 V) at 7 bar ( at 20mA, i.e. 10 V) the ambient pressure (1 bar) must be
added.
The entry is carried out as follows: 0..8 bar.
