ENDRESS+HAUSER  PTP31-A1A13H1AC1A

Pressure switch for monitoring absolute and gauge pressures in gases, vapours, liquids and dust with metallic process isolating diaphragm;

• Finely graduated measuring ranges from vacuum to 400 bar (6000 psi)
• Versions for use in hygienic applications
• Electronic versions
• one PNP switch output
• two PNP switch outputs
• PNP switch output with additional analog output 4...20 mA (active)

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

The process pressure acting upon the metallic process isolating diaphragm of the sensor is transmitted to a resistance bridge via a fluid. The change in the output voltage of the bridge is proportional to the pressure and can be measured directly.
