Mounting the OAT, RAT, and MAT Sensors

STE-1411/12/13/14 Bendable Copper Sensor
Use a bendable copper sensor for easily-accessible mixed air sections and outside air hoods. If the mixed
air section is not easily accessible, a flexible cable sensor may be used. If the unit does not have an easily-
accessible outside air hood, a rigid steel probe may be used.
1. Cut a hole in the mixed air chamber of the unit large enough to feed the copper probe from the back of the
enclosure.
2. Insert the sensor probe into the mixed air chamber, bend the probe tubing to cover the air path, and secure
as needed.
NOTE: Maintain a minimum bend radius of six inches to prevent damage to the wires or sensors.
3. Fasten the enclosure to the unit by drilling holes in the side of the unit and threading screws through the
mounting holes in the case.
4. For the cable leading to the AFMS controller, attach conduit to the 1/2" NPT threaded connection hole at
the bottom of the enclosure as needed.
5. Open the cover by pulling slightly on the latch on the right side of the enclosure while pulling on the cover.
STE-1415/6/7 Flexible Cable Sensor
A flexible cable sensor may be used if the mixed air section is not easily accessible.
1. Cut a hole in the mixed air chamber of the unit large enough to feed the sensor cable from the back of the
sensor enclosure.
