Trane SEN102 Chiller Temperature Sensor Assembly

Description:

The Trane SEN102 6-foot chiller temperature sensor is an OEM thermistor sensor assembly used in Trane commercial chiller systems to accurately monitor water, refrigerant, or process fluid temperatures for precise system control and equipment protection. Commonly installed in Trane air-cooled and water-cooled chillers, this temperature sensor provides continuous feedback to the chiller controller, enabling efficient compressor staging, capacity control, freeze protection, and fault diagnostics. HVAC service technicians and maintenance personnel use the SEN102 sensor for replacement, repair, preventive maintenance, and restoration of Trane commercial cooling systems.

Applications:

The Trane SEN102 temperature sensor is designed to provide accurate temperature measurement within chiller water and refrigerant circuits, ensuring reliable operation of the chiller control system. It is commonly used in commercial office buildings, hospitals, schools, manufacturing facilities, central chiller plants, and industrial process cooling systems where precise temperature monitoring is essential for energy efficiency and equipment protection. Trane chiller controllers use thermistor-based temperature sensors to monitor evaporator and condenser temperatures, generate system diagnostics, and regulate cooling performance.
