Function and system design

Measuring principle - process pressure measurement

Devices with ceramic process isolating diaphragm (Ceraphire®)

The ceramic sensor is an oil-free sensor, i.e. the process pressure acts directly on the robust ceramic process isolating diaphragm and causes it to deflect. A pressure-dependent change in capacitance is measured at the electrodes of the ceramic substrate and the process isolating diaphragm. The measuring range is determined by the thickness of the ceramic process isolating diaphragm.

Advantages:

•Guaranteed overload resistance up to 40 times the nominal pressure

•The ultrapure 99.9% ceramic (Ceraphire®, see also "www.endress.com/ceraphire") ensures:

–Extremely high chemical durability

–High mechanical durability

•Can be used in absolute vacuum

•Small measuring ranges

4Ceramic process isolating diaphragm

Devices with metallic process isolating diaphragm

The process pressure deflects the metal process isolating diaphragm of the sensor and a fill fluid transfers the pressure to a Wheatstone bridge (semiconductor technology). The pressure-dependent change in the bridge output voltage is measured and evaluated.

Advantages:

•Can be used for high process pressures

•Fully welded sensor

•Slim, flush-mounted process connections available
