Description
The Copeland 30A46-105 mercury flame sensor is designed for use in standing pilot gas heating systems to monitor pilot flame presence and ensure safe operation. Featuring a 12-inch sensing element, this control detects heat from the pilot flame and acts as a safety device by interrupting the gas supply if the flame is lost. Commonly used in furnaces and other gas-fired equipment, this mercury-type sensor provides reliable flame verification in systems that do not use electronic flame rectification. The 30A46-105 is suitable for replacement and retrofit applications where a thermal-based pilot safety control is required.
