About the APS Absolute Pressure Transducer

The pressure transducers of the DPS type series are suitable for detection of positive and negative gauge pressure or differential pressure of non-aggressive gases. Optional there is an absolute pressure version APS available. These robust versions can be applied in laboratories and under industrial conditions. Important criteria such as long-term stability, linearity and good reproducibility are guaranteed through their sturdy mechanical construction. Temperature drift is minimised through targeted compensation of every sensor. The wear-free inductive measurement system allows for almost maintenance-free operation.

The integrated electronic system provides a pressure-proportional voltage signal output of 0 … 10 V (option: current signal 0(4) …20 mA). This allows an interference-free transmission of signals even over comparatively large distances. For strongly varying pressures a dampening function is included.

Applications APS

  • HVAC
  • Clean room technology
  • Medical technology
  • Filter technology
  • Finishing pass measurement
  • Level measurement (bubbling-through method)
  • Flow velocity measurement (pitot tube, orifice disk)
