Duct mounted humidity/temperature
transmitter
HTRT2500(-420) are wall mounted humidity and temperature
transmitters for relative humidity and temperature measurement in air
handling systems. Available with 0...10 V DC (HTRT2500) or
4...20 mA (HTRT2500-420) output signal, and passive PT1000 signal.
Installation
Mount the transmitter on a wall. It should be located where the air can
circulate freely. Avoid locations where it can be exposed to distur-
bances that may influence the readings, i.e. near doors, radiators, on
sunlit walls etc.
When mounted in contaminated environments the transmitter's mem-
brane filter should be exchanged for a sintered brass filter.
Wiring
Connect supply voltage and output signals according to the diagram
for the unit being installed.
Connect passive PT1000 signal either between terminals 6-7 or 5-8.
