TW-MODBUS-T3 DISPLAY

HYGRASGARD® TW-MODBUS-T3

Item No. 1201-1281-3401-020
EAN 4 251325 617558

Patented quality product (pro-dynamic cross convection patent no. DE 10 2012 015 726.6)

Calibratable dew point control switches HYGRASGARD® TW - Modbus - T3 incl. strap ⁄ with detached sensor head, with Modbus connection. It reliably detects formation of dew by means of its humidity and temperature sensor (no conductivity measurement) and, thanks to its patented measuring method, pro-dynamic cross convection, yields an exact measurement result, 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 sensor is suitable for ceiling and duct installation or for integration in equipment. Fine adjustment by the user is possible.
