Lochinvar PLT30009 - Flame Sensor with Gasket

Maintaining consistent burner flame rectification is essential for combustion safety and sustained equipment uptime. The Lochinvar PLT30009 flame sensor, supplied with the 100073343 gasket, detects the presence of the burner flame to communicate directly with the ignition control module. By providing a stable signal path for ionization current, this assembly prevents ignition failures and ensures your boiler responds reliably to heating demands.

This sensor functions by extending a high-grade conductive rod into the combustion zone. As the flame envelops the rod, it rectifies the AC current from the control board into a DC microamp signal. The integrated ceramic insulator prevents current leakage to the burner chassis, ensuring the control board receives a precise, interference-free reading for optimal combustion monitoring.

Key System Performance Baselines:

• Flame Rectification Accuracy: Converts AC to DC microamp signals for precise ignition monitoring.
• Thermal Durability: Engineered with high-grade conductive materials to withstand intense combustion environments.
• Leakage Prevention: Integrated ceramic insulator prevents electrical shorting to the burner chassis.
• Installation Integrity: Includes 100073343 gasket to maintain a secure, gas-tight seal at the mounting point.

⚠️ Application Profile: Designed specifically for Lochinvar boiler units requiring flame sensing rectification in residential and commercial heating systems where reliable ignition control is mandated.
