DUCT TEMPERATURE SERIES
Installation & Operation Instructions
DT2630
GENERAL INFORMATION
The DT2630 is a battery operated wireless duct sensor
that gives the exibility and ease of installation for
monitoring duct temperatures wirelessly using
900MHz spread spectrum technology rather than
costly hardwire installations. The single point probe is
0.25" O.D., made of 304 stainless steel, and is available
in 4", 6", 8", 12", and 18" lengths to t most applications.
The DT2630 can be ordered with the standard
enclosure or NEMA 4X enclosure depending on the
speci cations required. The DT2630 will send the
temperature wirelessly to the RM2432D receiver that
converts the wireless signal to voltage input for use
with a DDC controller, or to a transceiver which will
send the data to a BAS using BACnet, Modbus, or
Lonworks protocol. Transmission distance in a typical
building is 200-300 feet horizontal depending on the
layout and construction of the building, and one oor
above and one oor below the transceiver. Sensor
distance and reliability can be increased with the
addition of a RR2552B(s) repeater.
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
strati cation), and not blocked by obstructions.
Strati cation and obstructions can cause sensing
errors. An example is downstream from a heating
or cooling coil.
MOUNTING INSTRUCTIONS
Drill a 7/8" 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 mounting screws. Use the
enclosure ange as a guide, or use the dimensions
listed below to measure out.
