Description
The Reznor 271993 is an 18″ averaging temperature sensor designed to provide accurate, representative air temperature measurements across a duct or air stream. By averaging temperatures across multiple points rather than relying on a single-point reading, this sensor helps HVAC control systems respond to true average conditions — improving comfort, efficiency, and equipment protection.
Engineered as a genuine Reznor OEM replacement part, the 271993 is built to integrate seamlessly with compatible Reznor heating and ventilation equipment. Its 18″ sensing element length makes it well-suited for medium-sized duct applications where uniform temperature sampling is essential.
