  • Factory-adjusted attenuation of the output signal of up to 5 s possible (optional)
  • Can be calibrated

Description

Differential pressure transmitter available in a range of precision classes for measurement of positive or negative differential pressures

These differential pressure transmitters are available in a wide range of precision classes and therefore suitable for applications in the heating, air conditioning and ventilation industries as well as sophisticated laboratory applications. An optional display allows measurement values to be read directly on-site in Pa, kPa or mmH2O. An optional time constant (up to 5s) allows the instrument to generate an attenuated output signal, even under fluctuating pressure conditions. The instrument is available with an ISO factory calibration or DAkkS calibration certificate (optional).

Measurement ranges
50 / 100 / 250 / 500 Pa
1 / 2.5 / 5 / 10 / 20 / 50 / 100 kPa
