This industrial shutter assembly periodically blocks the sensor's line of sight, allowing the burner controller to verify the integrity of the ultraviolet sensor and detection circuitry during run conditions. Engineered with a robust 1-inch NPT connection and explosion-proof NEMA 7 housing, it delivers continuous, failsafe performance in severe-duty environments without compromising system uptime.\u003c\/p\u003e\n\n\u003ch3\u003eFeatures\u003c\/h3\u003e\n\u003cul style=\"list-style-type: square;
