RIGID AVERAGING
Four Point Averaging, Nickel RTD
The ACI Nickel Rigid Averaging Series features a stainless steel, probe style sensing element with two 12 inch 22 AWG Etched Teon colored lead wires to dierentiate the dierent 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 benets 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 sensor aren’t easily installed. As an
added benet, the stainless steel probe also oers 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. Actual sensor length should be selected based upon 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 Certicates are available as referenced in the ordering grid.
Applications: Air Handlers, Roof Top Units, Mixed Air/Discharge/Supply Air Temperature Monitoring, Data Centers, Hospitals
