DUCT WITHOUT BOX
Flange Mounted Duct Sensor, Thermistor
The ACI Thermistor Duct without Box Series features a stainless steel probe with two 22 AWG
Etched Teon colored lead wires to dierentiate the dierent sensor types. The sensors in this
series are manufactured using ACI’s proven double encapsulation process to eliminate the
eects of moisture upon the sensors and increased response times using our high quality,
thermally conductive epoxy. The duct style sensor is designed to be used in smaller duct
applications and includes an insulation pad for sealing your duct as well as to dampen
vibration. For best results, the sensor length should be determined by the actual width or
diameter of your duct such that the tip of the probe is in 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 Duct without Box Series can be ordered with optional plenum rated cables and NIST
Certicates. Please contact ACI for more information regarding this sensor or to discuss your application in further detail. Other options may be
available upon request.
Applications: Roof Top Units, Air Handlers, Monitoring Supply/Discharge/Return/Mixed Air Temperatures
