KTU* Series

KELE Universal-Mount Thermistor and RTD Sensors

The Kele KTU* Series Universal-Mount Thermistor and RTD Sensors provide remote temperature sensing in multiple applications such as duct, OSA, and immersion installations for building automation systems. The active sensing element is a highly stable thermistor material or platinum RTD. The sensing element is sealed with a thermally conductive compound in a 4-7/8" (12.38 cm) long stainless steel probe and is attached to a 2.5" (6.35 cm) square enclosure. The tabs on the enclosure provide mounting ears for direct duct mounting and are easily removable if they are not needed. This multipurpose enclosure minimizes the number of stock parts required to handle multiple applications.
