Suited for large-duct mixed air monitoring, this averaging duct temperature sensor reads 32 to 167°F (0 to 75°C) along 50' (15.2 m) of flexible plenum-rated cable element with a 1000 Ω nickel RTD element. In addition, nine sensing points average the full duct cross-section. It includes nylon wire ties and mounts and a galvanized steel NEMA 1 enclosure.

The ACI Nickel Flexible Averaging Series features an 18 AWG Plenum Rated cable sensing element with two, 12" 22 AWG Etched Teflon colored lead wires to differentiate the different sensor types. All sensors are manufactured with 4 or 9 sensing points determined by the length of the sensing element. Averaging sensors provide a better average temperature of the air inside larger ducts when compared to a single point sensor.
The flexible averaging sensors are limited to applications where operating temperatures are limited to 32 to 158°F (0 to 75°C) or high humidity, chemical resistance and UV Light Air Treatment Systems aren’t required. Each of the sensing elements is sealed using a dual wall adhesive lined heat shrink tubing to provide a level of moisture protection to each of the sensing elements. The sensor length should be determined by the dimensional size of your duct.
Our standard enclosure options include a galvanized junction box “-GD” or plastic duct enclosure with hinged cover “-PB”. Each unit includes nylon wire ties and mounts for standard mounting. Optional copper capillary or universal plastic mounting clips, NEMA/IP Rated weather proof enclosures and NIST Certificates are available as referenced in the ordering grid.
