FLEXIBLE AVERAGING
Multipoint Averaging Sensor, Thermistor
The ACI Thermistor Flexible Averaging Series features an 18 AWG Plenum Rated cable sensing
element with two, 12 inch 22 AWG Etched Teon colored lead wires to dierentiate the
dierent sensor types. The sensors in this series are multi-point. Averaging sensors that will
provide a better overall average temperature of the actual air inside larger ducts when
compared to that of a single point sensor. All exible averaging sensors are limited to being
used in applications where operating temperatures are limited and high humidity, chemical
resistance, and UV light sources aren’t required. Each of the sensing elements is protected
using a dual wall adhesive lined heat shrink tubing to provide a basic level of moisture
protection. The sensor length should be determined by the size of your duct. 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 mounting. Optional copper capillary or universal plastic mounting clips, NEMA/IP Weather proof enclosures and NIST Certicates are
available as referenced in the ordering grid on the back of the product data sheet.
Applications: Air Handlers, Roof Top Units, Mixed Air/Discharge/Supply Air Temperature Monitoring, Data Centers, Hospitals
