Application
The pressure transmitter SITRANS P210 for gauge pressure is
used in the following industrial areas:
Mechanical engineering
Shipbuilding
Power engineering
Chemical industry
Water supply
Design
Device structure without explosion protection
The pressure transmitter consists of a piezoresistive measuring
cell with a diaphragm installed in a stainless steel enclosure. It
can be used with a connector per EN 175301-803-A (IP65), a
round plug M12 (IP67), a cable (IP67) or a cable quick screw
connection (IP67) connected electrically. The output signal is
between 4 and 20 mA or 0 and 10 V.

Function
The pressure transmitter measures the gauge pressure of liquids
and gases as well as the level of liquids.
Mode of operation
SITRANS P210 pressure transmitters (7MF1566-...), functional diagram
The stainless steel measuring cell has a thin-film resistance
bridge to which the operating pressure p is transmitted through
a stainless steel diaphragm.
The voltage output from the measuring cell is converted by an
amplifier into an output current of 4 to 20 mA or an output voltage
of 0 to 10 V DC.
The output current and voltage are linearly proportional to the in-
put pressure.
