Description
The Trane SEN01123 1.125″ Air Probe Sensor is an OEM temperature-sensing part used to measure air temperature within HVAC systems. It operates as a thermistor-effective probe that converts changes in air temperature into resistance signals, which are interpreted by the system control board to regulate heating, cooling, and airflow operation. In air handlers, rooftop units, and packages used in commercial and residential climate control applications, it is installed in the airflow stream or duct section where accurate ambient sensing is required.
