Trane SEN00249 Duct Temperature Sensor Assembly

Description:

The Trane SEN00249 duct temperature sensor is an OEM thermistor sensor used in Trane commercial HVAC systems to monitor supply or discharge air temperature within ductwork for precise temperature control, equipment protection, and energy-efficient operation. Commonly installed in Trane air handlers, rooftop units, VAV systems, and commercial air distribution equipment, this duct-mounted sensor provides continuous temperature feedback to the HVAC controller for heating, cooling, and changeover control. HVAC service technicians and maintenance personnel use the SEN00249 sensor for replacement, repair, preventive maintenance, and restoration of Trane commercial HVAC systems. The sensor is designed for a 40°F to 140°F (4°C to 60°C) operating range with a 0.31-inch diameter probe.

Applications:

The Trane SEN00249 duct temperature sensor is designed to accurately measure supply or discharge air temperature and transmit temperature data to the building automation or unit controller for proper HVAC operation. It is commonly used in commercial office buildings, hospitals, schools, retail facilities, industrial buildings, air handling units, rooftop systems, and VAV installations where precise duct temperature monitoring is essential for maintaining occupant comfort and system efficiency. The sensor can also support heat/cool changeover control in standalone HVAC applications.
