1 Siemens AG 206 Overview 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 A (IP65), a round plug M2 (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 0 V. Device structure with 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 A (IP65) or a round plug M2 (IP67) connected electrically. The output signal is between 4 and 20 ma. The SITRANS P200 pressure transmitter measures the gauge and absolute pressure of liquids, gases and vapors. Ceramic measuring cell Gauge and absolute measuring ranges to 60 bar (5 to 000 psi) For general applications Benefits High measuring accuracy Rugged stainless steel enclosure High overload withstand capability For aggressive and non-aggressive media For measuring the pressure of liquids, gases and vapors Compact design Application The SITRANS P200 pressure transmitter for gauge and absolute pressure is used in the following industrial areas: Mechanical engineering Shipbuilding Power engineering Chemical industry Water supply Function The pressure transmitter measures the gauge and absolute pressure of liquids and gases as well as the level of liquids. Mode of operation p U const. SITRANS P200 pressure transmitters (7MF ), functional diagram The ceramic measuring cell has a thin-film resistance bridge to which the operating pressure p is transmitted through a ceramic 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 0 V DC. The output current and voltage are linearly proportional to the input pressure. U I I 0, Siemens FI US Edition /5
