- Series DPS: positive and negative gauge pressure, differential pressure, optional bi-directional
- Series APS: absolute pressure
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)
