Tips: What is a duct temperature sensor and how does it work?

A duct temperature sensor is a device used to measure the temperature of the air inside ventilation ducts. It is commonly installed in heating, ventilation and air conditioning (HVAC) systems to help regulate the operation of the system by sensing temperature changes within the ducts. The principle of operation is that a probe inside the sensor comes into contact with the duct air, which senses the temperature and converts it into an electrical signal that is transmitted to the control system. Based on this data, the system automatically adjusts heating or cooling equipment to ensure a comfortable indoor environment.
