**4X** | The ACI Thermistor Duct Series features a stainless steel probe with two, 22 AWG Etched Teflon Om Wal colored lead wires to differentiate the different sensor types.  The sensors in this series are ll. manufactured using ACI’s proved double encapsulation process to eliminate the effects of OC 7 moisture on the sensors and increased response times from our high quality, thermally iZ jeJ conductive epoxy.  The duct sensor is designed to be used in smaller duct applications and includes an insulation pad for  sealing your duct and dampening vibration.  The sensor length **GD** should be determined by the width or diameter of your duct such that the tip of the probe 8) Se, reaches the approximate center of the duct.  Our standard enclosure options are the galvanized enclosure  “-GD” or plastic duct enclosure with 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 on the back of the product data sheet. 

**Applications:** Roof Top Units, Air Handlers,  Supply/Discharge/Return/Mixed Air Temperatures 

**The ACI Thermistor 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.**
