ST-U* Series

Precon Universal-Mount Thermistor and RTD Sensors

The Precon Model ST-U Universal Mount Sensor from PreCon provides precise remote temperature sensing in multiple applications such as duct, OSA, and immersion installations for Building Automation Systems, BAS. The active sensing element is a highly stable precision 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. These sensors have tabs on the enclosure to provide mounting ears for direct duct mounting. They can be easily removed if they are not needed. This multipurpose enclosure minimizes the number of stock parts required to handle multiple applications.
