Combustion Stability Monitoring

The 89429E0030 Flame Sensor utilizes ultraviolet-sensitive photodiode technology with 360° optical detection range for real-time combustion verification. Borosilicate glass lens maintains optical clarity under continuous soot exposure. Shock-mounted sensor head absorbs 15g vibration loads in engine compartment environments. Nickel-plated brass housing with NPT 3/4" thread ensures corrosion-resistant mounting in exhaust manifolds. Triple-sealed cable gland prevents moisture ingress during pressure washing. Spectral filtering eliminates false triggers from sunlight or welding arcs. Automatic gain control adjusts sensitivity based on combustion chamber conditions. Diagnostic-ready output provides flame presence confirmation through 0-5V analog signaling. Fail-safe design triggers engine protection protocols upon flame instability detection. Optimized for 5-35Hz flame flicker frequencies in diesel combustion cycles. Continuous self-test function monitors sensor integrity during operation. Field-proven reliability across 20,000+ service hours in refuse collection and urban transit applications.
