PRECAUTIONS
• DO NOT RUN THE WIRING IN ANY CONDUIT
WITH LINE VOLTAGE (24/120/230 VAC).
GENERAL INFORMATION
The Duct sensor is a single point temperature
sensor that is designed for use with electronic
controllers in commercial heating and cooling
building management systems. It is available
with multiple thermistor or RTD options.
For optimal temperature readings, follow these
tips:
•
Duct probe should be placed (3) to (4) duct segments
down from any bend or obstructions and away from
90° bends.
•
Mount the sensor on the top or sides of duct work;
mounting on the bottom risks damage due to
moisture.
•
The sensor should be mounted in the middle of the
duct where air circulation is well mixed (no
stratification), and not blocked by obstructions.
Stratification and obstructions can cause sensing
errors. An example is downstream from a heating or
cooling coil.
MOUNTING INSTRUCTIONS
Drill a 3/8” hole in the duct and insert the probe through
the hole until the foam pad is tight to the duct. Drill pilot
holes for the (2) mounting screws. Use the enclosure
flange as a guide, or use the dimensions listed below to
measure out.
