10K Type 3 with 11K Shunt Thermistor
Duct Averaging Units feature closed cell foam to seal the probe insertion hole and to absorb vibration. Mounting tabs allow for easy installation directly to the wall of the duct. All Duct Averaging Units have etched Teflon lead wires and double encapsulated sensors to create a watertight package that can withstand high humidity and condensation and 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 are able to measure temperature along their entire length. Nylon tie straps are provided for mounting. Duct Averaging Units come standard with a 2Ûx4Û steel J-Box but are also available with no box or three styles of enclosure: Weatherproof WP, Weather Tight EU, BAPI-Box or BAPI-Box 2. The metal WP enclosure carries a NEMA 3R rating, while the ABS polymer EU carries an IP66 rating and is available in a UV-resistant material. The BAPI-Box and BAPI-Box 2 are made of UV-resistant polycarbonate and carry an IP66 rating. BAPI also offers optional liquid-tight fittings.
