Installation and Maintenance Guidelines
Installation Requirements: Use flange or threaded mounting. Ensure the detector is aligned with the flame combustion area, avoiding direct exposure to high-temperature flue gas. Use shielded cables for the signal line and keep away from sources of strong electrical interference.
Maintenance Recommendations: Clean the detector window regularly (calibrate every 6-12 months). Use specialized cleaning tools to avoid scratching the lens. If flame recognition anomalies occur, check the wiring connections, probe sensitivity, and impedance matching potentiometer.
Troubleshooting:
False Alarms/Missing Alarms: Clean the quartz lens if the probe lens is contaminated. If the impedance matching potentiometer is over-adjusted, slowly adjust it clockwise until the indicator light illuminates.
Line Interference: Humid environments may increase distributed capacitance; adjust the potentiometer in reverse until the relay releases.
Advantages and Alternatives
High Reliability: Industrial-grade high-temperature resistant materials and optimized optical components extend service life; quick-disconnect connectors reduce maintenance time.
Compatibility: As a standard replacement for GE’s combustion management system, it is fully compatible with original equipment manufacturer (OEM) specifications and supports upgrades of older sensors for land-based/marine gas turbines.
Extended Functions: Supports digital/analog signal output, seamlessly integrates with DCS, PLC, SCADA, and other systems for remote monitoring and data acquisition.
Performance Advantages:
High Sensitivity and Interference Resistance: SiC material is sensitive to long-wave UV light and has strong penetration capabilities through fuel/vapor mist, suppressing false alarms caused by welding arc light and sunlight.
