Description
The Trane SEN00204 Temperature Sensor is a probe-effective thermistor used to monitor air or surface temperature and send resistance-based response to the control board in HVAC systems. It operates within a 90F to 250F sensing range and uses a slim 0.025-inch diameter, 5-inch long probe for insertion into airflow ducts, coils, or heat exchanger locations where precise temperature measurement is required. It is installed in air handlers, rooftop units, and chiller systems as part of the temperature control and safety input loop, helping regulate heating and cooling cycles and maintain stable system operation through accurate temperature monitoring.
