COPPER AVERAGING
Bendable Multipoint Copper, Thermistor
The ACI Thermistor Copper Averaging Series features a copper sensing element with AWG
Etched Teon colored lead wires to dierentiate the dierent sensor types. Each sensor is
manufactured with 4 or 9 sensing points determined by the length of the sensing element. The
averaging sensors provide a better average temperature of the air inside the duct when
compared to a single point duct sensor. Each of the elements is sealed to prevent moisture
intrusion and includes a foam pad to seal the duct and dampen vibrations. The benets of
using a copper sensing element is that it has improved thermal conductivity and higher
corrosion resistance than similar aluminum style averaging sensors. Additionally, copper has
been proven to have an antibacterial eect to many of the airborne contaminants, mold and
bacteria found in duct systems. Our standard enclosures include the galvanized “-GD” or plastic
duct enclosure with hinged cover “-PB”. Each unit includes nylon wire ties and mounts with
optional copper capillary and universal plastic mounting clips, NEMA/IP Rated Weather Proof enclosures and NIST certicates as referenced on the
back of the product data sheet.
Applications: Air Handlers, Roof Top Units, Mixed Air/Discharge/Supply Air Temperature Monitoring, Data Centers, Hospitals
