This \u003cstrong\u003eflame rectification rod\u003c\/strong\u003e features a high-grade \u003cstrong\u003estainless steel rod\u003c\/strong\u003e paired with a robust \u003cstrong\u003ehigh-temperature ceramic insulator\u003c\/strong\u003e to handle the extreme thermal stress within the combustion chamber. When the burner ignites, the sensor generates a essential \u003cstrong\u003emicroamp signal\u003c\/strong\u003e (typically 0.5 to 10 μA) that communicates flame presence to the \u003cstrong\u003efurnace control board\u003c\/strong\u003e. If the signal is lost or falls below the threshold, the system initiates a safety shutdown to prevent the accumulation of unburned gas.\u003c\/p\u003e\n\u003cp\u003eThis \u003cstrong\u003e90-degree offset sensor\u003c\/strong\u003e is a direct replacement for \u003cstrong\u003eRheem, Ruud, and WeatherKing\u003c\/strong\u003e units, including popular series such as the \u003cstrong\u003e80PJ, 90RJ, and R801T\u003c\/strong\u003e. It features a standard \u003cstrong\u003e1\/4 inch male quick connect\u003c\/strong\u003e termination for a secure electrical bond. With a 2-1\/2 inch probe length from the mounting flange to the tip, it ensures precise placement within the flame path for reliable rectification.
