Measuring cell
+100 mbar....+40 bar
(+1.5 psi....600 psi)
Field of application
The Ceraphant PTC31B is a price-attractive pressure switch with ceramic, vacuum tight measuring cell for safe measurement and monitoring of absolute and gauge pressure. The pressure switch with compact design is extremely stable and high vacuum resistant up to 0bar abs. The IO-Link capability allows easy integration and parametrization of the device.
Pressure switch with ceramic sensor diaphragm for monitoring absolute and gauge pressures in gases, vapors, liquids and dusts.
Process connections: Threads
Process temperature: -25 to +100°C (-13 to +212°F)
Pressure: -1/0 up to +40bar (-15/0 up to +600psi)
Accuracy: ±0.3%
Benefits
Integrated switching electronics for decentral and economic process monitoring and control
Easy function check and information on site thanks to LEDs and digital display
Dry capacitance ceramic sensor (Ceraphire) and minimum span of up to 0 to 20mbar provide reliable insight to the process
High process availability for vacuum applications and applications with abrasive media
IO-Link reduces costs and complexity due to easy configuration and flexible integration in all fieldbus systems.

Powerful IO-Link Function Block Library for the Siemens TIA Portal
Thanks to the newly available free software library, all IO-Link
capable measuring devices from Endress+Hauser can now be
integrated into a Siemens TIA Portal environment much more
easily and significantly faster than ever before. The streamlined
process of device integration not only brings drastic time savings,
but the user can now get by without any programming knowledge
at all.Language:
