ACI Nickel RTD Rigid Probe Averaging

Features

  • Stainless steel, probe-style sensing element with two 12-inch 22 AWG Etched Teflon colored lead wires.
  • Manufactured with 4 sensing points to provide a better average temperature in smaller to medium-sized ducts.
  • Each of the elements is hermetically sealed to prevent moisture intrusion and includes an integrated foam pad to seal the duct and dampen vibrations.
  • It can be installed easily in either a horizontal or vertical position, like that of a single-point duct sensor.
  • Can be used in applications where longer Flexible or Copper averaging sensors aren’t easily installed.
  • The stainless steel probe also offers a higher level of corrosion resistance to chemicals and moisture in the air stream.
  • The actual sensor length should be selected based on the overall dimensional area of your duct.
  • ACI’s standard enclosures include the galvanized junction box “-GD” or plastic duct enclosure with the hinged cover “-PB”.
  • Optional NEMA/IP-rated Weather Proof 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 Rigid Averaging Series features stainless steel, probe-style sensing element with two 12-inch 22 AWG Etched Teflon colored lead wires to differentiate the different sensor types. The Nickel Rigid Averaging sensors are manufactured with 4 sensing points to provide a better average temperature in smaller to medium-sized ducts when compared to that of a single point duct sensor or the longer Flexible and Copper averaging sensors can’t be easily incorporated. Each of the elements is hermetically sealed to prevent moisture intrusion and includes an integrated foam pad to seal the duct and dampen vibrations. Some of the benefits of using a stainless steel Rigid Averaging sensor is that it can be installed easily in either a horizontal or vertical position, like that of a single point duct sensor, and can be used in applications where a longer Flexible or Copper averaging sensors aren’t easily installed. As an added benefit, the stainless steel probe also oers a higher level of corrosion resistance to chemicals and moisture in the air stream when compared to that of the Flexible or Copper Averaging sensors. The actual sensor length should be selected based on the overall dimensional area of your duct. ACI’s standard enclosures include the galvanized junction box “-GD” or plastic duct enclosure with the hinged cover “-PB”. Optional NEMA/IP-rated Weather Proof enclosures and NIST Certificates are available as referenced in the ordering grid.
