Für jede Anwendung die richtige Lösung [Translate]
The room sensor HYGRASGARD® FSFM/ FSFTM in the in-wall housing is used for measuring the relative humidity and temperature of the air. It converts the measured values into a standard signal of 0 -10 V.
A digital, long-term stable sensor is used for humidity and temperature measurement. Relative humidity [% r.H.] is the quotient of water vapour partial pressure divided by the saturation vapour pressure at the respective gas temperature.
The in-wall sensor is mounted in high-quality panel switch programmes, ideally of the brands Gira, Berker, Merten, Jung, Siemens or Busch-Jaeger (using in-wall adapters) either individually or in combination with light switches, socket outlets, etc.
It is used in non-aggressive, dust-free environments, in refrigeration, air conditioning and clean room technology, and in interior rooms, such as living rooms, offices, hotels, etc
