Description
The Kele ST-FZ24-25 is a 10K OHM averaging temperature sensor engineered for reliable duct air temperature measurement in commercial HVAC and building automation system (BAS) applications. Featuring a flexible averaging element, this sensor samples temperature across the full cross-section of a duct or air handler, delivering a true mean temperature reading rather than a single-point measurement — ideal for large duct installations where temperature stratification can occur.
Key Features
- 10K OHM resistance element for broad compatibility with BAS controllers and DDC systems
- Averaging sensor design captures representative duct temperature across the full duct cross-section
- Flexible sensing element suitable for installation in large air handlers and ductwork
- Designed for commercial HVAC building automation and energy management applications
- Kele quality construction for long-term reliability in demanding HVAC environments
Applications
- Commercial air handling units (AHUs)
- Large rectangular and round ductwork
- Building automation and direct digital control (DDC) systems
- Mixed-air, supply-air, and return-air temperature sensing
- Energy management and HVAC optimization systems
Why Choose the Kele ST-FZ24-25?
Averaging sensors are the preferred solution wherever temperature uniformity across a duct cannot be assumed. By integrating temperature readings along the full length of the sensing element, the ST-FZ24-25 eliminates the measurement error associated with single-point sensors in large or stratified airstreams. The 10K OHM output ensures plug-and-play compatibility with the majority of commercial BAS and DDC controllers on the market today.
