Functions
The duct sensor acquires PM2.5 & PM10 concentrations. The output value is the moving av-
erage of latest sensor data within 10 s.
The duct sensor acquires the relative humidity in the air duct via its capacitive humidity sens-
ing element whose electrical capacitance changes as a function of relative humidity.
The electronic measuring circuit converts the sensor’s signal to a continuous DC 0...10 V or
DC 0...5 V or 4...20 mA signal, corresponding to a relative humidity range of 0...100 %.
The duct sensor acquires the temperature in the air duct via its sensing element whose elec-
trical character changes as a function of the temperature.
The change is converted to an active DC 0...10 V or DC 0...5 V or 4...20 mA output signal
( 0...50 °C or -35...+35 °C).
Mechanical design
The fine dust duct sensor consists of a housing, a printed circuit board, connection terminals,
a mounting flange, and an immersion rod. The immersion rod of the QSM2162 has a meas-
uring tip.
The bisectional housing consists of a base and a removable cover (snap-on design). The
measuring circuit and the setting elements are located on the printed circuit board inside the
cover, the connection terminals are located on the base.
The humidity and temperature sensing elements are located at the end of the measuring
probe and are protected by a filter cap.
Cable entry is made via the cable entry gland M16 (IP54) supplied with the sensor, to be
screwed into the housing.
Immersion rod and housing are made of plastic and are rigidly connected.
The sensor is fitted with the mounting flange supplied with the sensor. The flange must be
placed over the immersion rod and then secured as per the required immersion depth.
The setting elements are located inside the cover.
PM2.5 and PM10 have same DIP switch settings.

Notes:
*) If the signal output of X1 & X2 is 10 V or 20 mA, the cause of the error is one of the follow-
ing:
●The selected measuring range of PM2.5 & PM10 is below the measured PM2.5 or PM10
value. E.g., if the selected measure range is 0…50 μg/m3, but the measured PM2.5 or
PM10 value is 100 μg/m3, the signal output of X1 & X2 will be 10 V or 20 mA. Selecting a
higher range resolves this error.
●If the signal output is still 10 V or 20 mA after changing the selected measuring range,
the cause is a PM2.5 communication error.
In the following table:
●High means the signal output of terminal is 10 V/5 V/20 mA after 60 s.
●Low means the signal output of terminal is 0 V/0 V/4 mA after 60 s.

Notes
Security
CAUTION
National safety regulations
Failure to comply with national safety regulations may result in personal injury and property
damage.
●Observe national provisions and comply with the appropriate safety regulations.
Engineering
Powering the sensor requires a transformer for safety extra low-voltage (SELV) with sepa-
rate windings for 100 % duty. When sizing and protecting the transformer, comply with all lo-
cal safety regulations.
When sizing the transformer, consider the sensor's power consumption.
For correct wiring, see the related device data sheets.
Observe all permissible line lengths.
Cable routing and cable selection
Note that when routing cables, the longer the cable runs and the closer the cables, the
greater the electrical interference. Use shielded cables in EMC-prone environments.
Twisted pair cables are required for both secondary supply lines and signal lines.
Mounting
To ensure degree of protection IP54, the sensor must be fitted with the cable entry pointing
downward!
Mount the sensor where it can be easily accessed by service.
●If used after humidifier, a certain distance is required between humidifier and sensor, so
that the vapor or mist generated by the humidifier can evaporate before reaching the
sensor. This distance is marked on the diagram as BM. The minimum distance between
the humidifier and the sensor must be no less than BM.
●Avoid any impact or shock to the sensing elements in the immersion rod.
●To avoid sunlight damage, do not mount the sensor on a rooftop. To ensure correct op-
eration, the sensor’s ambient temperature must be in the range of -5…45 °C.

curacy expected.
●Do not install the sensor in a vertical duct.

Replacing AQS2100
NOTICE! Only trained engineers may replace the sensor module.
The sensor module must be replaced under the following conditions:
●QSM2162 (PM2.5 + r.h. + temperature): An output signal of 10 V/5 V/20 mA is provided
at signal outputs X1 and X2 and an output signal of 0 V/4 mA at signal output X3.
●QSM2100/QSM2162 (PM2.5 + PM10 + temperature): An output signal of
10 V/5 V/20 mA is provided at signal output X1 and an output signal of 0 V/4 mA at sig-
nal output X2.
Replacing the sensor module:
NOTICE! As the replacement on QSM2162 and QSM2100 is identical, the steps to re-
place the QSM2162 sensor module serve as an example.

FCC (Federal Communications Commission)
This device complies with part 15 of the FCC rules. Operation is subject to the following two
conditions:
1. This device may not cause harmful interference;
2. This device must accept any interference received, including interference that may cause
undesired operation.
Changes or modifications not expressly approved by the party responsible for compliance
could void the user's authority to operate the equipment.
NOTE: This equipment has been tested and found to comply with the limits for a Class B dig-
ital device, pursuant to part 15 of the FCC Rules. These limits are designed to provide rea-
sonable protection against harmful interference in a residential installation. This equipment
generates, uses and can radiate radio frequency energy and, if not installed and used in ac-
cordance with the instructions, may cause harmful interference to radio communications.
However, there is no guarantee that interference will not occur in a particular installation. If
this equipment does cause harmful interference to radio or television reception, which can be
determined by turning the equipment off and on, the user is encouraged to try to correct the
interference by one or more of the following measures:
●Reorient or relocate the receiving antenna.
●Increase the separation between the equipment and receiver.
●Connect the equipment into an outlet on a circuit different from that to which the receiver
is connected.
●Consult the dealer or an experienced radio/TV technician for help.
FDA (Food and Drug Administration)
This device complies with IEC/EN 60825-1:2014, 21 CFR 1040.10 and 1040.11 except for
conformance with IEC 60825-1 Ed. 3, as described in Laser Notice No. 56, dated May 8,
2019. It is subject to the following conditions:
●Class 1 laser product
●LASER RADIATION for laser module
●655 nm, CW (continuous wave), for laser leakage < class 1 laser product limit (0.39 mW)
NOTE: The sensor module of fine dust duct sensor is fully enclosed, so no potentially haz-
ardous radiation is accessible during use. In order to avoid inadvertent exposure to hazard-
ous laser radiation, do not disassemble the housing of sensor module during operation or
maintenance. If the housing is broken, do not use and replace with a new module.
