Dew point control switches HYGRASGARD® TW-Modbus-T3

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

Calibratable dew point control switch HYGRASGARD® TW - Modbus - T3 (compact variant incl. strap) or TW - Modbus - external (detached variant), with Modbus connection, in an impact-resistant plastic housing with quick-locking screws, optionally with/ without display, to exactly detect the relative humidity (0…100% RH) and the temperature (–35...+80 °C) and to detect various parameters in humidity measurement. The dew formation in particular is reliably determined thanks to its patented measuring method, the pro-dynamic cross-convection (no conductivity measurement). International system of units SI (default) can be switched to Imperial (via Modbus).

The surface-contact sensor is applied in a non-aggressive, dust-free environment and is suitable for installation in ceilings, ducts and devices. It is used in the refrigeration, air conditioning and clean room technology, engineering rooms, hotels and conference facilities.

A long-term stable, digital humidity and temperature sensor guarantee exact measurement results. These measurands are used to internally calculate the following parameters that can be retrieved via Modbus: relative humidity, absolute humidity, mixture ratio, dew point, enthalpy (ignoring atmospheric air pressure) and ambient temperature.
