Differential pressure transmitter PU/PI/PIZ

Differential pressure transmitter for air-conditioning applications


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).
