Mounting
Duct Temperature Sensor, Averaging (Copper Tubing)
STE-1411/1412/1413/1414
Installation Guide
The averaging temperature sensor incorporates several discrete sensors encapsulated at equal distances
across the length of the copper tubing probe. The
complete assembly acts as a single sensor to monitor 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 humidier elements.

Temperature sensors can be aected by air stratication 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 stratication, the coldest air tends to
be toward the boom of the duct. Hence, one of the
sensors inside the tubing should be near the boom
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, aach conduit to a hole in one
of the sides.

Connections and Wiring
More Information
1. Feed wires from the controller through the
conduit opening.
2. Make connections to the two sensor wire leads
with either bu-splices or solder. (Using wire
nuts is not recommended.) The two-wire sensor is
not polarity sensitive.
3. Plug the conduit with plumber’s puy, painter’s
puy, caulk, or other sealant to prevent air
inltration.
