The Cerabar S pressure transmitter measures the pressure of gases, steam/vapour and liquids and can be used in all areas of chemical and process engineering.

Operating principle 

Ceramic sensor

The system pressure acts directly on the rugged ceramic diaphragm of the pressure sensor deflecting it by a maximum of 0.025 mm. A pressure-proportional change in the capacitance is measured by the electrodes on the ceramic substrate and diaphragm.

The measuring range is determined by the thickness of the ceramic diaphragm.

Metal sensor

The process pressure deflects the separating diaphragm with a filling liquid transmitting the pressure to a resistance bridge. The bridge output voltage, which is proportional to pressure, is then measured and processed.

Level measurement

The hydrostatic pressure of a column of liquid enables its level to be measured continuously by a pressure transmitter if the densityρof the liquid is known.
