Unlike a traditional thermocouple which has a hot junction made of a physical union of two conductors, the model TCC creates a virtual junction at the maximum temperature point. With this virtual junction, the sensor is able to detect a maximum temperature along its entire length. It can even detect, in real time, the maximum temperature even if the location of the hot spot changes. By setting up multiple sensors to cover a large surface area, monitoring of different zones can be achieved to indicate a more direct location of the hot spot.
