Baumer PP20R measures relative pressure in pressure ranges from 0 to 0.25 bar and 0 to160 bar. It is available in a variety of models about the accuracy, the output signal (current 4 to 20 mA and voltage 0 to10V, 0 to 5V, and 0 to 2V), and electronic and process connections.

The sensor is suitable for use in applications such as pressure measurement in braking systems, cooling systems for traction units, and controlling and regulating the pantograph contact pressure. Insulation strength is up to 1.5 kVac, which minimizes the risk of damage caused by voltage differences in the device, thereby increasing both its own operating safety and that of the entire system.

  • Tested according to EN 50155
  • High dielectric strength of 1,5 kV AC exceeding the standard according EN 50155
  • High accuracy over a wide temperature range (-40 … 125 °C) due to active compensated temperature compensation
  • Extended EMC immunity compared to EN 50121-3-2
  • Traceability according to GS1 standard
  • Designed for a wide range of railway applications as e.g. pantograph pressure control, coolant recirculating pumps, and railway brake systems
