Description
The Fireye 69ND1-1000K4 is a precision ionization flame rod engineered for industrial burner management systems that demand dependable, continuous flame detection. Using the proven flame rectification method, this 12-inch rod conducts a small electrical signal through the gas flame to confirm safe, active combustion — enabling automatic safety shutdown the moment flame failure is detected.
Built from high-temperature resistant metal, the 69ND1-1000K4 is purpose-built for the harsh thermal environments found in boilers, furnaces, and process heating equipment. Its 1/2″ NPT threaded mount ensures a secure, leak-free installation, while the 12-inch rod length provides the extended reach needed to position the sensing tip accurately within the flame envelope.
This flame rod integrates seamlessly with Fireye flame safeguard controls and burner management systems, supporting safe ignition sequencing, continuous flame monitoring, and reliable fault response.
