HYGRASGARD® RFTF-Modbus P 5L LCD

Quality product for the HVAC sector, accuracy ± 2 %

The calibratable room sensor HYGRASGARD® RFTF - Modbus with Modbus connection,
in an attractive plastic housing (Baldur 2) with snap-on lid, lower part with 4-hole
mounting, optionally with ⁄ without display, measures air humidity (0...100 % RH) and
temperature (- 35...+80 °C).


The following parameters are calculated internally from these measured variables
calculated internally,
which can be queried via Modbus: absolute
humidity, mixing ratio,
dew point temperature,
enthalpy (neglecting
of the atm. air pressure).


International
system of units
SI (default) can be switched to Imperial (via Modbus). For device variant
wModbus device variant, the W-Modbus (wireless) replaces the RTU cable, the BMS connection takes place
wirelessly via a W-Modbus gateway.
A long-term stable, digital humidity and temperature sensor guarantees precise measurement results.
The sensor is calibrated at the factory, an environment-related
fine adjustment by a specialist
is possible. Modbus sensor with electrically isolated RS485 Modbus interface,
switchable
bus terminating resistor,
DIP switch for setting the bus parameters and
bus address
in de-energized state, internal LEDs for telegram status display
and two-line
display (illuminated, individually programmable in the 7-segment area and dot-matrix area).
