This is a pilot flame sensing thermocouple typically used in commercial gas appliances. It converts heat from the pilot flame into a small electrical signal to help ensure safe burner operation. The thermocouple has a length of 48" and an output of 20–30 mV. It features 11/32"-32 coaxial threading to provide a proper fit in compatible pilot assemblies. The probe is heated by the pilot flame and sends a signal to the gas safety system to maintain operation during normal use. This component is commonly found in commercial kitchens, including restaurants, bakeries, and institutional kitchens. It helps support reliable ignition and steady burner operation during cooking. When the thermocouple begins to deteriorate, issues such as pilot flame outages, delayed ignition, and improper burner shutdown can occur. Replacing the thermocouple can help restore flame sensing and support stable heating performance.
