The Southbend 1182580 Thermocouple provides reliable flame sensing for commercial cooking equipment. This 24" thermocouple, rated at 20–30 mV for the 1970 Series, works by generating a small electrical signal when heated by the pilot flame. The signal keeps the gas safety valve engaged during operation and automatically interrupts gas flow if the flame is extinguished. By supporting responsive flame monitoring, it helps improve operational safety, maintain stable burner performance, and reduce unexpected shutdowns, making it a practical replacement component for demanding commercial kitchen environments.
