Duct Temperature Sensor, Averaging (Copper Tubing)
STE-1411/1412/1413/1414
Mounting
The averaging temperature sensor incorporates sev-
eral discrete sensors encapsulated at equal distances
across the length of the copper tubing probe. The
complete assembly acts as a single sensor to moni-
tor the average temperature in a duct. Averaging
elements are not recommended for high humidity
applications.
The copper tubing can be installed onto hangers in
the duct using tube clamps or wire ties. It 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 inside the tubing should be near the bottom
of the duct.
1. Cut a hole in the duct large enough to feed the
copper probe 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 probe into the duct, bend the
probe tubing to cover the air path, and secure
as needed. Maintain a minimum bend radius
of six inches to prevent damage to the wires or
sensors.
4. For the cable leading to the building automation
system controller, attach conduit to a hole in one
of the sides.
