Room sensor for humidity/temperature HYGRASGARD® RFTF-wModbus

The calibratable room sensor HYGRASGARD® RFTF - Modbus with Modbus connection, in an elegant plastic housing (Baldur 2) with snap-on lid, lower part with 4-hole mounting, optionally with/without display, measures humidity (0...100 % RH) and temperature (0...+50 °C) with wModbus (- 35...+80 °C). The following parameters are calculated internally from these measured variables and can be queried via Modbus: absolute humidity, mixing ratio, dew point temperature, enthalpy (disregarding atm. air pressure). International system of units SI (default) can be switched to Imperial (via Modbus). With device variant wModbus, the W-Modbus (wireless) replaces the RTU cable, the BMS connection is radio-based via an W-Modbus gateway.




A long-term stable, digital humidity and temperature sensor guarantees exact measurement results. The sensor is calibrated at the factory; fine adjustment by a specialist is possible depending on the environment. Modbus sensor with electrically isolated RS485 Modbus interface, switchable bus terminating resistor, DIP switch for setting the bus parameters and bus address in the de-energized state, internal LEDs for telegram status display and two-line display (illuminated, individually programmable in the 7-segment range and dot-matrix range).
