Process pressure measurement  

Pressure sensors detect the pressure in pipes or closed vessels. Inside the sensor, the deflection of a membrane is converted into a measuring signal. Different measuring cells are used for pressure detection.

The advantages

Ceramic measuring cells offer the advantage of excellent long-term stability and high overload resistance. Metallic measuring cells also cover higher measuring ranges.
