SENSOR TECHNOLOGY
TRANSDUCER ‘DIFFERENTIAL PRESSURE – AIR’
TECHNICAL DATA
APPLICATION
Housing colour: Housing material:
grey
The microprocessor-controlled pressure transducers are suitable for detecting overpressure, underpressure or differen- tial 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.
