Dew point control switch HYGRASGARD® TW-Modbus

The universal surface-contact sensor serves to detect various parametres in humidity measuring. Measurands include relative humidity and ambient air temperature. These measurands are used to calculate various parametres internally. The following parametres can be retrieved via Modbus: relative humidity [%r.H.], absolute humidity [g/m³], mixture ratio [g/kg], dew-point temperature [°C], enthalpy [kJ/kg] (ignoring atmospheric air pressure) and ambient temperature [°C].
The control switch is used in non-aggressive, dust-free environments, in refrigeration, air conditioning and cleanroom engineering, hotels, engineering rooms, meeting and conference facilities. The measuring transducers provide precise detection of temperature and humidity. A digital, long-term stable sensor is used as a measuring element for humidity and temperature. Fine adjustment by the user is possible. The sensor is suitable for ceiling and duct installation or for integration in equipment.
