Product Overview
The Siemens QRB1 is a high-sensitivity photoresistive flame detector designed specifically for the supervision of oil flames in the visible light spectrum. Unlike UV detectors, the QRB1 is optimized to detect the yellow light emitted by the combustion of liquid fuels. It is primarily used in conjunction with Siemens burner controls (such as the LOA, LMO, LAL, or LBH series) to provide reliable flame monitoring for oil burners in intermittent operation, ensuring safe ignition and continuous flame supervision.
Key Features
- Visible Light Sensitivity: Features a photoresistive sensor tuned to the yellow light spectrum, making it ideal for monitoring luminous oil flames.
- Compact Plug-in Design: The small, space-saving housing allows for easy installation even in tight burner configurations or small-scale industrial heating units.
- Intermittent Operation: Certified for use in systems that require at least one controlled shutdown every 24 hours to verify safety functions.
- Multiple Sensitivity Levels: Available in different sensitivity versions (e.g., standard or high sensitivity) to ensure optimal detection regardless of the burner’s light intensity.
- Versatile Mounting Options: Can be supplied with or without a mounting flange or specialized soft plastic plug, ensuring a secure fit on various oil burner housings.
- Integrated Cable: Comes with pre-attached, heat-resistant connecting cables in various lengths to simplify wiring during installation.
Core Advantages
- Cost-Effective Oil Monitoring: Provides a highly reliable and budget-friendly alternative to UV detection for standard oil-fired applications without compromising safety.
- Simplified Maintenance: The plug-in design allows for effortless removal, cleaning, and replacement, minimizing the time required for routine burner servicing.
- Proven Field Reliability: As a global standard for oil burner technology, the QRB1 series is renowned for its long-term stability and consistent performance in both domestic and industrial environments.
- Global Safety Compliance: Manufactured to meet rigorous European safety standards, providing the necessary assurance for international trade and equipment manufacturing.
