Wall mounted humidity sensor
Wall mounted humidity/temperature sensor
HRT is a wall mounted humidity sensor for measuring relative
humidity in air handling systems.
Available with output signal 0 - 10V DC (HRT) or 4 - 20mA
(HRT-420).
HTRT is a wall mounted humidity and temperature sensor for
measuring relative humidity and temperature in air handling
systems.
Available with outputs 0 - 10V DC (HTRT) or 4 - 20mA (HTRT-
420).
Installation
Mount the sensor on a wall. It should be located where the air
can circulate freely. Avoid locations where it can be exposed to
disturbances that may influence the readings, i.e. near doors,
radiators, on sunlit walls etc.
N.B. For accurate function make sure to mount the unit
vertically with the cable entry at the lower left-hand corner.
Wiring
Connect supply voltage and output signals according to the
diagram for the unit being installed.
Supply voltage:
HRT and HTRT: 24V AC +/-20% or 15...35V DC.
HRT-420 and HTRT-420: 20...28V DC
Output signals:
Humidity: 0...10V DC (4...20mA) corresponding to 0...100% RH.
Measuring range:
1...9V DC (5.6...18.4mA) corresponding to10...90% RH.
Accuracy:
HRT and HTRT: +/-3% RH.
HRT-420 and HTRT-420:+/-3%RH.
Temperature (HTRT and HTRT-420): 0...10V DC (4...20mA)
Accuracy at 20°C: +/-0.5K.
External load impedance:
HRT and HTRT: minimum 10kW .
HRT-420 and HTRT-420: maximum 500W .
EMC emission and immunity standards:
This product conforms with the requirements of European EMC
standards CENELEC EN 50081-1 and EN 50082-1 and carries
the CE mark.
