Alerton Duct Sensor

The Alerton Thermistor Duct Series features a stainless steel probe with two, 22 AWG Etched Teflon coloured lead wires to differentiate the different sensor types. The sensors in this series are manufactured using Alerton’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 centre 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. Duct sensors are widely used in roof top units, air handlers, supply/discharge/return/mixed air temperatures.
