Room, humidity and temperature sensor or measuring transducer


The room sensor and measuring transducer HYGRASGARD® FSFTM - Modbus in the in-wall
enclosure, optionally with potentiometer, is used to measure the relative humidity and
temperature of the air, and for setpoint adjustment. The following parameters are calculated
internally from the measured values: relative humidity [% r. H.], absolute humidity [g ⁄ m³],
mixture ratio [g ⁄ kg], dew point temperature [°C], enthalpy [kJ ⁄ kg] (ignoring atmospheric air
pressure) and room temperature [°C]. The parameters are queried via the Modbus interface.

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, no setpoint
adjustment possible) either individually or in combination with light switches, socket outlets,

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.
