Product Description
The HYGRASGARD® FSFTM - Modbus room sensor and measuring transducer with in-wall enclosure and optional potentiometer is used to measure the relative humidity and temperature of the air, and for setpoint adjustment. The following parametres 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 parametres can be 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 transmitter is mounted either individually or in combination with light switches, socket outlets, etc. in high-quality panel switch brand programmes, such as preferably from Gira, Berker, Merten, Jung, Siemens or Busch-Jaeger (with in-wall adapters, no setpoint adjustment possible).
It is used in non-aggressive, dust-free environments, in refrigeration, air conditioning and cleanroom engineering, and in interior spaces, such as living rooms, offices, hotels, etc.
