The Cerabar is a pressure sensor for the measurement of absolute and gauge pressure in gases, vapors, liquids and dust. The Cerabar can be used internationally thanks to a wide range of approvals and process connections.
Ceramic process isolating diaphragm: 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.
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.
Features include:
High reproducibility and long-term stability
Customized measuring ranges
Flush-mounted process connection as option
Specs at a glance
Media
Gases, vapors, liquids and dust
Output
4 to 20 mA
Process temperature
–40 to +100 °C (–40 to +212 °F)
Measuring ranges
From –100 to +100 mbar (–1.5 to +1.5 psi) to –1 to +400 bar (–15 to +6000 psi)
