Your benefits
This compact pressure switch impresses with the latest in
technology being used:
- Integrated switching electronics for decentral and economic process monitoring and control
- Quick and flexible process integration thanks to modular connections
- High reproducibility and long-term stability
- Function check and information on site thanks to LEDs and digital display
- Ceraphire ® process isolating diaphragm: corrosion proof, abrasion-proof and extremely overload-resistant
- Excellent accuracy and briefest response time right to the smallest measuring range
- Operation and visualisation also with personal computer and ReadWin ® 2000 or FieldCare®
- Upper part of housing can be rotated by 310°, therefore best readability of measured values in all orientations
- DESINA compliant
- 3A and EHEDG approved
Measuring principle
The process pressure acts on the ceramic process isolating diaphragm and the pressure-dependent change in
capacitance of the ceramic sensor is measured. A microprocessor evaluates the signal and switches the output
or outputs the corresponding measured value.
The ceramic sensor is a dry sensor i.e. no fill fluid is needed for pressure transmission. This means that the
sensor can fully support a vacuum. Extremely high durability, on a par with the material Alloy, is achieved
through the use of the highly pure material Ceraphire ® as a ceramic.
