Type II Duct Thermistor 4", 10 kΩ (Plastic Enclosure)

FEATURES

The ACI Thermistor Duct Series features a stainless-steel probe with two, 22 AWG Etched PTFE colored lead wires to differentiate the different sensor types. The sensors in this series are manufactured using ACI’s proved double encapsulation process to eliminate the effects of moisture on the sensors and increased response times from our high quality, thermally 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 should be determined by the width or diameter of your duct such that the tip of the probe reaches the approximate center of the duct. On larger ducts, you may want to refer to our Rigid or Bendable Copper Averaging sensor for increased sensing points and better temperature control.

• The ACI Thermistor Duct Series is covered by ACI's Five Year Limited Warranty
