Hobart 00-348358-00001 Thermopile
The Hobart 00-348358-00001 Thermopile is a flame-sensing temperature-to-voltage component used in commercial gas cooking and heating equipment to support safe and reliable operation. This 36-inch coaxial thermopile generates a consistent electrical signal in the range of approximately 250–750 millivolts when exposed to heat from a pilot flame, enabling the control system to confirm flame presence and maintain proper gas valve function. If the flame is lost, the voltage drops and the system reduces or cuts fuel flow to help prevent unsafe conditions. By converting thermal energy into an electrical signal without external power, it supports dependable ignition control, consistent flame sensing, and operational safety in professional foodservice appliances.
