THERMOCOUPLE 24"

Technical Description

Product Type: Thermocouple (Pilot Safety Sensor)
Length: 24 inches
Application: Gas water heaters, furnaces, and boilers with standing pilot systems.

Function

A 24-inch thermocouple is a safety device used in gas-fired appliances to detect the presence of a pilot flame. When heated by the pilot flame, the thermocouple generates a small electrical signal (millivolts) that keeps the gas control valve open. If the pilot flame goes out, the signal stops and the gas valve automatically shuts off, preventing gas leaks.
