7MF1567 SITRANS P220 pressure transmitter

■Application

The pressure transmitter SITRANS P220 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), around plug M12 (IP67), a cable (IP67) or a Quickon 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 P220 pressure transmitters (7MF1567-...), functional diagram

The stainless steel measuring cell has a thick-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 input pressure.
