Air pressure sensor

Applications

  • building services
  • industrial applications
  • weather stations

Absolute pressure

is measured inside the cost effective, practical and robust standard housing. The technical design enables the on site changeover of the measuring range, as well as the choice of the output signal. This universally applicable sensor is the right solution for price conscious customers. It distinguishes itself through its low maintenance and easy operation.

  • cost effective
  • OEM variant with 3 modes of operation
  • applicable with/ on data loggers in energy-saving mode (e.g. solar operation)
  • 1 instrument with 2 ranges of pressure measurement and 3 standard outputs - adjustable with plug-in jumpers
