ACI Thermistor Copper Averaging

Features

  • Provide a better average temperature of the air inside the duct when compared to a single-point duct sensor.
  • Each element is sealed to prevent moisture intrusion and includes a foam pad to seal the duct and dampen vibrations.
  • Improved thermal conductivity and higher corrosion resistance than similar aluminum-style averaging sensors.
  • Copper has been proven to be antibacterial to many of the airborne contaminants, mold, and bacteria found in duct systems.

Automation Components, Inc. (ACI) creates, manufactures, and distributes building automation sensors for the heating, ventilation, and air conditioning (HVAC) Industry. Dpstar is ACI Authorised Distributor in Malaysia. Our product lines include Temperature Sensors, Relative Humidity Sensors, Current Sensors, Pressure Sensors, Gas Sensors, and Wireless Sensors.

The ACI Thermistor Copper Averaging Series features a copper sensing element with AWG Etched Teflon colored lead wires to differentiate the different 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 element is sealed to prevent moisture intrusion and includes a foam pad to seal the duct and dampen vibrations. The benefits 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 effect 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 certificates as referenced on the
back of the product datasheet.

Applications

  • Air Handlers
  • Roof Top Units
  • Mixed Air/Discharge/Supply Air Temperature Monitoring
  • Data Centers
  • Hospitals

The ACI Thermistor Bullet Probe Series is covered by ACI’s Five (5) Year Limited Warranty.
