ACI Nickel RTD Flexible Averaging

Features

  • 18 AWG Plenum Rated cable sensing element with two, 12-inch 22 AWG Etched Teflon colored lead wires.
  • Manufactured with 4 or 9 sensing points determined by the length of the sensing element.
  • Provide a better average temperature of the air inside larger ducts when compared to a single-point sensor.
  • Limited to applications where operating temperatures are limited to 0 to 75ºC (32 to 158ºF) 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.  The sensor length should be determined by the dimensional size of your duct.
  • Standard enclosure options include a galvanized junction box “-GD” or plastic duct enclosure with a 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 weatherproof enclosures.
  • NIST Certificates are available as referenced in the ordering grid.

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 Nickel Flexible Averaging Series features an 18 AWG Plenum Rated cable sensing element with two, 12-inch 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 0 to 75ºC (32 to 158ºF) 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 a 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 weatherproof enclosures, and NIST Certificates are available as referenced in the ordering grid.

Applications

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

The ACI Nickel RTD Flexible Averaging Series is covered by ACI’s Five (5) Year Limited Warranty.
