Faston Type thermocouple for gas cookers

Faston Type thermocouple for gas cookers

Product number:ESTH-015

Quick Overview: Gas Thermocouple Safety Protection System Working Principle: A thermocouple consisting of two pieces of dissimilar metals joined together at one end (hot junction). When the hot junction is heated, the thermocouple produces DC voltage to the other end. It powers thermoelectric gas valves and when used is a safety feature on gas hearth products. Loss of the pilot can removes the electrical current and shuts off the gas supply to the burner.
