## **Duct Sensor, Nickel RTD** **4X** | The ACI Nickel Duct Series features a 1/4" diameter stainless steel probe with two, 22 AWG Om Wal Etched Teflon colored lead wires to differentiate the different sensor types. The Nickel sensors ll. are manufactured using ACI’s proven double encapsulation process to eliminate the effects of OC 7 iZ jeJ moisture on the sensors as well as increased thermal response times from our high quality, thermally conductive epoxy. The duct style sensor is a single point sensor designed to be used **GD** in smaller duct applications and includes an insulation pad for sealing the duct and dampening vibration. For best results, the sensor length should be determined by the width or diameter of 8) Se, your duct such that the tip of the probe is in the approximate center of the duct. Our standard enclosure options include the galvanized junction box “-GD” or plastic duct enclosure with the hinged cover “-PB”. On larger ducts, you may want to refer to our Rigid or Bendable Copper Averaging sensor for increased sensing points and better temperature control. This series can be ordered with optional NEMA/IP rated weather proof enclosures and NIST Certificates as referenced in the ordering grid. **Applications:** Roof Top Units, Air Handlers, Monitoring Supply/Discharge/Return/Mixed Air Temperatures **The ACI Nickel Duct Series is covered by ACI's Five (5) Year Limited Warranty. The warranty can be found in the front of ACI's Sensors & Transmitters catalog, as well as on ACI's website, www.workaci.com.** ## PRODUCT SPECIFICATIONS **==> picture [453 x 359] intentionally omitted <==** **----- Start of picture text -----**
