Passive sensors for acquiring the air temperature in air ducts.
The duct temperature sensors are for use in ventilation and air conditioning plants as:
• Supply or extract air temperature sensors
• Limit sensors, e.g. for minimum limitation of the supply air temperature
• Reference sensors, e.g. for shifting the room temperature as a function of the out-
side temperature
• Measuring sensors, e.g. for measured value indication or for connection to a building
automation and control system

When ordering, please give name and type reference, e.g.:
Duct temperature sensor QAM2120.040
The sensor is supplied complete with mounting flange AQM63.0 and, if required,
mounting clamps AQM63.3.
All systems or devices capable of acquiring and handling the sensor’s passive output
signal.
The sensor acquires the air temperature via its sensing element whose resistance
changes as a function of the temperature. The signal is delivered to a suitable controller
for further handling.

The duct temperature sensor consists of the following components:
• Two-sectional plastic housing comprised of base with connection terminals and removable cover (snap-on design)
• Fully active, flexible probe with sensing element which acquires the average temperature
The connection terminals can be accessed after removing the cover. Cable entry is
made via a grommet which, if required, can be replaced by a cable entry gland M16
(IP 54).
After fitting the mounting flange, the sensor can be installed in 6 different immersion
positions so that the sensor housing is always located outside the insulation for layers
up to 70 mm. The probe with a length of 2 or 6 m is to be fitted across the air duct with
the help of the mounting clamps supplied with the sensor.

Mounting examples
• For supply air temperature control: Downstream from the fan, if the fan is located
after the last air handling unit. Otherwise, after the last air handling unit with a minimum distance of 0.5 m
• For extract air temperature control: Always upstream of the extract air fan
• As a limit sensor for the supply air temperature: As close as possible to the air outlet
into the room
• For dew point control: Immediately after the spray trap of the air washer
Manually bend the probe so that it lies diagonally across the duct or in equally spaced
windings across the entire duct cross-section. The probe must not touch the duct wall.
The sensor is supplied complete with Mounting Instructions.
