The Air Duct Temperature Sensor is used to measure the level of air temperature in the duct work. This sensor devices are generally used in HVAC applications that are generally monitored by advanced technology in order to measure accurately and supervise the observation. As the air passes over the duct, the temperature of the duct changes and the sensor is used to measure the change of temperature in the duct. With the development and advancement of technology to such a huge extent, most of the new technology comes with this Air duct Temperature Sensor. It is most common commonly found in Electrical appliance and more or less used as a safety measure, which is supervised by a team of experts of the same field.
Use of Air Duct Temperature Sensor-
The thermistor which is present in the ducts of the temperature sensor which enables the engineers or the workers to monitor the temperature and work accordingly. The thermistor which is present in the Air Duct Temperature Sensor is not only present in the HVAC appliances and devices but also present in millions and millions of devices of our day to day usages such as Television, Mobile Phones, Computer, Water Pumps and Inverters as well. One example of the use of Thermistor is that when we use computers or laptops it tends to get hot with usage and it is then the processor in the appliances turns the fans in the Air Duct Sensors on in order to equalize the temperature and makes the temperature cooler than it was before. You must have noticed that once you start your computer, you hear the noise of your fan present in the computer getting started as well. It starts in order to neutralize the processor from getting hot. If there was no cooling agent present in the computer or other electronic appliances, it would have blasted due to the rise of temperature. So in order to prevent such a mayhem, the companies ensure the installation of the Air Duct Temperature Sensor in order to have a check on the temperature. You should have noticed if you are working on your computer, after a certain amount of time the temperature will rise and there after the temperature will slowly reduce courtesy of the Air Duct Temperature Sensor.
Disadvantage of Air Duct Temperature Sensor-
Again there is a disadvantage of this Duct Temperature Sensor. The only disadvantage is that once if the Thermistor is somehow destroyed, it is really very difficult to fix it. The problem one will face to repair it is quite expensive and it will almost bear the cost of a new device. So if once if the device is destroyed by any chance one needs to buy a new one considering the cost that will be spent on the recovery of the same.
The ducts are easily available in the market and the E- Commerce sites such as Amazon and E- Bay as well and it will cost between $ 50- $150 depending on the quality of the products.
