ACI Thermistor Flexible Averaging

Features

  • 18 AWG Plenum Rated cable sensing element with two, 12 inch 22 AWG Etched Teflon colored lead wires to differentiate the different sensor types.
  • The sensors are multi-point.
  • Provide a better overall average temperature of the actual air inside larger ducts when compared to that of a single-point sensor.
  • Used in applications where operating temperatures are limited and high humidity, chemical resistance, and UV light sources aren’t required.
  • The sensing element is protected using a dual wall adhesive lined heat shrink tubing to provide a basic level of moisture protection.
  • Each unit includes nylon wire ties and mounts for mounting.
  • Optional copper capillary or universal plastic mounting clips, NEMA/IP Weatherproof enclosures, and NIST Certificates are available.

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 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. The sensors in this series are multi-point. Averaging sensors provide a better overall average temperature of the actual air inside larger ducts when compared to that of a single-point sensor. All flexible 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 a hinged cover “-PB”. Each unit includes nylon wire ties and mounts for mounting. Optional copper capillary or universal plastic mounting clips, NEMA/IP Weatherproof enclosures, and NIST Certificates are available as referenced in the ordering grid 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.
