HYGRASGARD® RFTF-Modbus

Quality product for the HVAC sector, accuracy ± 2 %

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). International system of units SI (default) is set to Imperial (via Modbus). The following parameters are calculated internally from the measured variables and can be queried via Modbus:
relative humidity, absolute humidity, mixing ratio, dew point temperature, enthalpy (disregarding atm. air pressure) and temperature.
Available as room operating units in various types with control elements such as setpoint potentiometer (%), rotary switch (5-stage), presence button or five colored LEDs (color and mode configurable) to display the operating status.

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 galvanically 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).
