Room operating humidity and temperature sensor 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 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 (- 35...+80 °C).


The following parameters
are calculated internally from these measured variables,
which can be queried via Modbus: absolute
humidity, mixing ratio,
dew point temperature,
enthalpy (neglecting
the 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 precise measurement results.
The sensor is calibrated at the factory, and fine adjustment by the 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 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).
