DUCT WITHOUT BOX
Flange Mounted Duct Sensor, Platinum RTD
The ACI Platinum Duct without Box Series features a 1/4" diameter stainless steel sensing
element with two, 14 or 24 inch, 22 AWG Etched Teon colored lead wires to dierentiate the
dierent sensor types. The three-wire “-3W” option should be ordered if using with a 3-Wire
temperature transmitter or sensor conguration on your building management system or PLC
(Programmable Logic Controller). The purpose of the 3rd wire is to compensate for any
external lead wire resistance that will aect the accuracy of your sensors output signal. ACI
recommends the use of 18 AWG lead wires to reduce the external lead wire resistance when
using a Platinum RTD sensor and its lower sensor resolution. The sensors in this series are
manufactured using ACI’s proven double encapsulation process to eliminate the eects of
moisture upon the sensors as well as increased response times using our high quality, thermally conductive epoxy. The duct style sensor is a single
point sensor designed to be used in smaller duct applications and includes an insulation pad for properly sealing your duct as well as to dampen
vibration. 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, jacket materials and standard lead lengths.
Applications: Roof Top Units, Air Handlers, Monitoring Supply/Discharge/Return/Mixed Air Temperatures
