Application
The Cerabar T is a pressure transducer for measuring
absolute pressure and gauge pressure in gases, vapors,
liquids and dusts.
Hygienic and threaded connections are available as
process connections.
Your benefits
This compact pressure transducer impresses with its
well-engineered construction:
- High reproducibility and long-term stability.
- Finely graduated measuring ranges from vacuum up to 400 bar (6000 psi)
- Ceraphire ® ceramic sensor: corrosion-proof, abrasion proof and extremely overload-resistant
- Deployed for pressure monitoring up to SIL 2 as per IEC 61508/IEC 61511-1
- Sensors
- Dry capacitance ceramic sensor (Ceraphire ® ) for measuring ranges up to 40 bar (600 psi): overload-resistant, vacuum-proof, stable against alternating load
- Piezoresistive sensor with metallic process isolating diaphragm for measuring ranges up to 400 bar (6000 psi)
Measuring principle with analog output
The process pressure acting upon the metallic process isolating diaphragm of the sensor is transmitted to a
resistance bridge via a fluid. The pressure-proportional change of the bridge output voltage is measured and
processed further.
Measuring principle with switch output
The process pressure acting upon the metallic process isolating diaphragm of the sensor is transmitted to a
resistance bridge via a fluid. A differential amplifier creates a standard signal from the pressure-proportional
change in output voltage of the bridge. A comparator with an adjustable hysteresis compares this signal with
the pre-set switch point and then activates the transistor output.
