ACI Platinum RTD Rigid Probe Averaging

Features

  • Stainless steel probe with Etched Teflon colored lead wires to differentiate the different sensor types.
  • The three-wire “-3W” option should be ordered when using with a 3-Wire temperature transmitter or sensor configuration on your building management system or PLC (Programmable Logic Controller).
  • Include a continuous sensing element, which covers the entire length of the probe for a better average temperature over the entire length of the sensor when compared to that of a single point duct sensor or multi-point averaging sensor.
  • These sensors are hermetically sealed with epoxy to ensure that moisture and other contaminants can’t affect the sensing element.
  • The Rigid Averaging sensor also includes a foam pad to seal the duct and dampen vibrations once installed.
  • The sensor length determined by the width or diameter of your duct
  • Our standard enclosure options include the “-GD” galvanized or “-PB” plastic duct enclosure with hinged cover.
  • On larger ducts, our Platinum bendable copper averaging sensor can be used for larger ducts and increased coverage area.
  • This series can be ordered with optional NEMA/IP rated weather proof enclosures and NIST Certificates as referenced in the ordering grid.

The ACI Platinum Rigid Averaging features a stainless steel probe with Etched Teflon colored lead wires to differentiate the different sensor types. The three-wire “-3W” option should be ordered when using with a 3-Wire temperature transmitter or sensor configuration on your building management system or PLC (Programmable Logic Controller). The purpose of the 3rd wire is to compensate for external lead wire resistance that affects the accuracy of your sensor output. ACI recommends the use of 18 AWG lead wires to reduce external lead wire resistance when using a Platinum RTD. The rigid averaging sensors include a continuous sensing element, which covers the entire length of the probe. This allows for a better average temperature over the entire length of the sensor when compared to that of a single point duct sensor or multi-point averaging sensor. These sensors are hermetically sealed with epoxy to ensure that moisture and other contaminants can’t affect the sensing element. The Rigid Averaging sensor also includes a foam pad to seal the duct and dampen vibrations once installed. The sensor length should be determined by the width or diameter of your duct such that the sensor covers most of the internal width or height of the duct. Our standard enclosure options include the “-GD” galvanized or “-PB” plastic duct enclosure with hinged cover. On larger ducts, our Platinum bendable copper averaging sensor can be used for larger ducts and increased coverage area. This series can be ordered with optional NEMA/IP rated weather proof enclosures and NIST Certificates as referenced in the ordering grid.
