IFM PI2794

Electronic Pressure Sensors

ifm offers a wide range of electronic pressure sensors to meet the requirements of various industrial applications. The ceramic-capacitive measuring cell, tried and tested millions of times, is complemented by a stainless steel measuring cell with thin-film or thick-film wire strain gauges (series PK, PV, PT) and a piezoresistive measuring technique (for pneumatic applications).

Robust Design

All units have robust housings and do not require moving parts such as pistons or springs. The result: The electronic air pressure sensor are extremely shock and vibration resistant and operate without any wear or maintenance.

Long-Term Stability

The tried and tested ceramic-capacitive measuring cell is corrosion-resistant and long-term stable. In the long run this guarantees continuous accuracy of the measured values. The sensors are resistant to dynamic pressure peaks and guarantee high overload resistance even in the case of extreme pressure peaks that occur for example with fast closing valves.

Versatile Applications

Units with wire strain gauge in thick-film technology on a stainless steel measuring cell are distinguished by their very compact and robust design. They can be used in almost all industrial areas. The welded stainless steel measuring cell without any seals ensures a high degree of safety, in particular for applications with gas pressures of up to 600 bar as well as in air-conditioning and refrigerating technology where aggressive coolants (freons) are used.
