ACI Platinum RTD Duct Without Box

Features

  • 1/4″ diameter stainless steel sensing element with two, 14 or 24 inch, 22 AWG Etched Teflon colored lead wires
  • The three-wire “-3W” option should be ordered if using with a 3-Wire temperature transmitter or sensor configuration on your building management system or PLC (Programmable Logic Controller).
  • 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 determined by the actual width or diameter of your 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.

Automation Components, Inc. (ACI) creates, manufactures, and distributes building automation sensors for the heating, ventilation, and air conditioning (HVAC) Industry. Dpstar is ACI Authorised Distributor in Malaysia. Our product lines include Temperature Sensors, Relative Humidity Sensors, Current Sensors, Pressure Sensors, Gas Sensors, and Wireless Sensors.

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 Teflon colored lead wires to differentiate the different sensor types. The three-wire “-3W” option should be ordered if using with a 3-Wire temperature transmitter or sensor configuration 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 affect 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 effects 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.
