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.

Material of parts coming in contact with the medium: Operating voltage: Ambient temperature: Permissible atmospheric humidity:

Ni, PU, Al, Au, Pyrex glass, silicone, Kovar, Duraplast, Ultem Plasic

15 – 30 VDC, 15 – 30 VAC

10 to 50 °C

max. 80% rel. humidity, non-condensing
