The thermocouple is a safety device that automatically cuts off the gas at the tap if the flame on the gas lines is accidentally extinguished.
At the end of this thermocouple, a calibrated probe transmits an electrical signal to an electrode incorporated in the gas tap.
This device is fitted to gas cooking appliances.
The thermocouple consists of 3 parts.
- 1 metal wire (nickel + chrome alloy - type K) inserted into 1 tube (nickel + aluminum (5%) + silicon alloy - type K).
Both ends: (tip and terminal) soldered as shown in the picture. - 1 copper tube serving as a channel for the first 2 parts.
When the tip is heated, the heat energy transformed into electrical energy creates a magnetic field. The latter is used to open the gas tap valve. In the absence of a flame, the spring relaxes and closes the gas supply. Thermocouples are characterized by a letter that determines the operating temperature range.
