What is a thermo coupler on cooktop?

A thermocouple is a device that measures temperature by converting a temperature difference into an electrical signal. In a cooktop, the thermocouple is used to measure the temperature of the pan or cooktop surface. This information is then used by the cooktop's control system to adjust the heat output.

Thermocouples are made of two dissimilar metals that are joined together at one end. When the junction of the two metals is heated, a small electrical current is generated. The amount of current that is generated is proportional to the temperature of the junction.

The thermocouple on a cooktop is typically located near the heating element. As the heating element heats up, the thermocouple generates an electrical current that is proportional to the temperature of the heating element. This electrical current is then sent to the cooktop's control system, which uses it to adjust the heat output.

Thermocouples are a very important part of a cooktop's control system. Without a thermocouple, the cooktop would not be able to accurately measure the temperature of the pan or cooktop surface, and it would not be able to adjust the heat output accordingly.

Here are some additional details about thermocouples on cooktops:

* Thermocouples are typically made of copper and constantan, which are two metals with different electrical properties.

* The thermocouple is usually located in a metal sheath to protect it from damage.

* The electrical current generated by the thermocouple is very small, so it is amplified before it is sent to the cooktop's control system.

* Thermocouples are very accurate and reliable, and they are used in a wide variety of applications besides cooktops, including ovens, refrigerators, and industrial machinery.
