Trane SEN102 Chiller Temperature Sensor Assembly

The Trane SEN102 is a 6-foot OEM chiller temperature sensor assembly that provides accurate temperature feedback for Trane commercial chiller control systems. This thermistor-based sensor uses an NTC output and features a probe/immersion installation with a 6 ft (1.83 m) cable designed to route to the chiller controller. It monitors water and refrigerant temperatures to support compressor staging, capacity control, freeze protection, and fault diagnostics, compatible with Trane commercial chillers (model dependent), helping optimize energy use and protect equipment in the system. Commonly installed in Trane air-cooled and water-cooled chillers, it serves chilled water circuits and refrigerant paths across commercial buildings such as offices, hospitals, schools, manufacturing facilities, central chiller plants, and other process cooling applications where precise temperature monitoring is essential.
