Description

Application

The Ceraphant PTP31B is a cost-effective pressure switch featuring a piezoresistive sensor designed for reliable measurement and monitoring of both absolute and gauge pressures. Its compact construction offers exceptional stability and can withstand overloads up to +400 bar. With IO-Link capability, the device facilitates seamless integration and easy parameterization.

This pressure switch is equipped with a metallic sensor diaphragm, making it suitable for monitoring absolute and gauge pressures in gases, vapors, liquids, and dusts.

Specifications:

  • Process Connections: Threaded
  • Process Temperature Range: -40 to +100°C (-40 to +212°F)
  • Process Pressure Range: 400 mbar to +400 bar (6 to +6,000 psi)
  • Accuracy: Up to ±0.3%

 


 

Benefits

  • Integrated switching electronics enable decentralized and cost-effective process monitoring and control.
  • On-site function checks and information display via LEDs and digital readout.
  • Overload-resistant sensor capable of withstanding pressures up to 400 bar.
  • Compact, flush-mounted process connections.
  • IO-Link technology simplifies configuration and integration, reducing costs and complexity across various fieldbus systems.
