TW-MODBUS EXTERN DISPLAY

HYGRASGARD® TW-MODBUS EXTERN

Item No. 1201-1211-3201-030
EAN 4 251325 610160

Quality product for HVAC sector, accuracy ± 2 %
calibratable dew point control switch HYGRASGARD® TW - Modbus incl. strap/ with detached sensor head, with Modbus connection, terminal box housing made of impact-resistant plastic, housing cover with quick-locking screws, with/ without optional display.
The universal surface-contact sensor is used to detect various parameters in humidity measurement. The relative humidity and temperature of the ambient air are measured. These measurands are used to calculate various parameters internally. The Modbus can be used to retrieve the following parameters: 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].
It is used in non-aggressive, dust-free environments, in the refrigeration, air conditioning and clean room technology, hotels, engineering rooms, meeting and conference facilities. The measuring transducers are designed for exact detection of temperature and humidity. A digital, long-term stable sensor is used as a measuring element for humidity and temperature measurement. Fine adjustment by the user is possible. The sensor is suitable for ceiling and duct installation or for integration in equipment.
