Averaging Duct Temp Sensors

Automated Logic’s Duct Averaging Temperature Sensors feature closed cell foam to seal the probe insertion hole and absorb vibration. Mounting tabs allow for easy installation directly to the wall of the duct. All units have etched Teflon leadwires and encapsulated sensors to create a watertight package that can perform under real world conditions.

Averaging probes should be used wherever there is a chance for stratified layers of hot and cold air. Averaging probes are made of bendable aluminum tubing and measure temperature along their entire length. Nylon tie straps are provided for mounting.

Duct Averaging Temperature Sensors come standard with a 2”x4” steel J-Box but are also available with No Box, a BAPI Box 4, or a BAPI-Box 2.
