Differential pressure transmitter with two-wire technology (cable-safer) for measurement of positive or negative differential pressures

Special features

  • High level of accuracy and long-term stability
  • Little zero point drift or hysteresis; largely independent of temperature
  • Measurement of positive and negative differential pressures
  • LCD display (optional)
  • Output signal 4 .. 20 mA
  • Factory-adjusted attenuation of the output signal of up to 5 s possible (optional)
  • Can be calibrated

This differential pressure transmitter reduces wiring costs thanks to its two-wire technology. An optional display allows measurement values to be read directly on-site in Pa, kPa or mmH 2 O. An optional time constant (up to 5s) allows the instrument to generate an attenuated output signal, even under fluctuating pressure conditions. 


  • Available with an factory calibration certificate or calibration certificate according to DKD-R 6-1 (optional).
