Duct Temperature Sensor, Averaging (Flexible)
STE-1415/1416/1417
Mounting
The averaging temperature sensor incorporates sev-
eral discrete sensors encapsulated at equal distances
across the length of the probe. The complete as-
sembly acts as a single sensor to monitor the average
temperature in a duct. Averaging elements are not
recommended for high humidity applications.

The sensors can be installed onto hangers in the
duct using tube clamps or wire ties. They should
be located in a straight section of duct away from
heating, cooling, or humidifier elements.
Temperature sensors can be affected by air stratifica-
tion in the duct, air leakage through the conduit
or other duct holes, and nearness to exterior walls,
a large thermal mass (e.g., concrete blocks), heat
sources, or wires with power.
Because of air stratification, the coldest air tends to
be toward the bottom of the duct. Hence, one of the
sensors should be near the bottom of the duct.
The flexible cable can be easily shaped to fit any duct
size but observe a minimum bend radius of two
inches to prevent damage to wires or sensors.
1. Cut a hole in the duct large enough to feed the
sensor cable through the back of the sensor
enclosure.
2. Fasten the enclosure to the duct by drilling holes
in the duct and threading screws through the
mounting holes in the case.
3. Insert the sensor cable into the duct, stringing the
cable to cover the air path, and secure as needed.
4. For the cable leading to the building automation
system controller, attach conduit to a hole in one
of the sides.
