Description
The ACI 123356 is a 10kOhm copper averaging thermistor sensor designed for precise temperature measurement across large duct cross-sections or extended spaces in commercial and industrial HVAC systems. Its 24-foot averaging element distributes sensing points along the full length of the element, providing a true mean temperature reading rather than a single-point measurement — eliminating hot and cold spots that can skew control decisions.
Key Features
- 10kOhm thermistor resistance output for compatibility with a wide range of building automation and HVAC controllers
- 24-foot copper averaging element for broad-area temperature sensing
- Copper construction delivers excellent thermal conductivity and long-term durability
- Averaging design eliminates single-point temperature bias in large ducts or air handlers
- Ideal for use with DDC systems, energy management systems, and building automation controllers
- Easy field installation with flexible element routing
Typical Applications
- Large supply and return air ducts
- Air handling unit mixed-air and discharge-air sensing
- Commercial and industrial HVAC zoning systems
- Building automation and energy management systems
