ACI Thermistor Rigid Probe Averaging

Features

  • ¼” Diameter stainless steel sensing element with two, 12 inch, 22 AWG Etched Teflon colored lead wires.
  • 4 sensing points in lengths from 12” to 48”.
  • The rigid averaging sensors will provide a better average temperature of the air inside the duct when compared to a single-point sensing element.
  • Each of the elements is hermetically sealed to prevent any moisture intrusion and includes an integrated foam pad to properly seal the duct and dampen vibrations when installed.
  • Mounts like a standard single-point duct sensor but include three additional sensing points for better control.
  • The sensor length should be determined by the size of your duct.
  • This series can be ordered with optional NEMA/IP rated weatherproof enclosures 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 Thermistor Rigid Averaging Series features a ¼” Diameter stainless steel 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 manufactured with 4 sensing points in lengths from 12” to 48”. The rigid averaging sensors will provide a better average temperature of the air inside the duct when compared to a single-point sensing element. Each of the elements is hermetically sealed to prevent any moisture intrusion and includes an integrated foam pad to properly seal the duct and dampen vibrations when installed. The benefit of using the rigid averaging sensor is that it mounts like a standard single-point duct sensor but includes three additional sensing points for better control. The sensor length should be determined by the size of your duct. Our standard enclosures include the galvanized junction box “-GD” or plastic duct enclosure “-PB” with the hinged cover depending on your preference. This series can be ordered with optional NEMA/IP rated weatherproof enclosures as referenced in the ordering grid.
