Transducer “Differential pressure – air”
Technical data
Application
Housing colour: Housing material:
grey
The microprocessor-controlled pressure transducers are suitable for detecting overpressure, under- pressure or differential pressure of non-aggressive gases. They are used in heating, ventilation or air conditioning applications as well as in clean room technology or for fine draft measurement. The pressure measurement is performed using a piezo-resistive pressure sensor.
