Outside humidity and temperature sensor HYGRASGARD® AFTF - SD - Modbus
Quality product for the HVAC sector, accuracy ±2%
Calibratable HYGRASGARD® AFTF-SD-Modbus outside humidity and temperature sensor with Modbus connection, terminal box housing made of impact resistant plastic, housing cover with quick-locking screws, with/without optional display.
The universal on-wall 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 Modbus device can serve to retrieve the following parametres: 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 temperature transmitter is used in non-aggressive, dust-free environments, in refrigeration, air conditioning and cleanroom engineering, in hotels, engineering rooms, meeting and conference facilities. The measuring transducer provides 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.
