Description
Introduction to Siemens QRA2 Photocell
The Siemens QRA2 Photocell, a leading product in the realm of flame monitoring and control, leverages global technical expertise and high standards to position itself as a market leader. This device ensures professional-grade flame detection, essential for industrial applications.
Key Features of Siemens QRA2 Photocell
Silicon Semiconductor Technology
The Siemens QRA2 Photocell uses a silicon semiconductor as its electrical conductor, converting light into electrical energy with high efficiency. This technology is crucial for the device’s reliability and accuracy in flame detection.
Wide Application Range
This photocell is extensively used in flame scanners, offering precise monitoring capabilities for various flame-based processes. Its versatility makes it suitable for a range of industrial burners.
Operational Mechanism
The QRA2 Photocell operates by detecting ultraviolet (UV) radiation emitted from gas or oil flames. It produces a flame signal within the UV spectrum range of 190 to 270 nanometers, ensuring accurate flame presence detection. Unlike visible light sensors, UV cells in the QRA2 are immune to interference from sunlight or shaded light.
Robust Construction
Constructed with materials like germanium semiconductors, the QRA2 is designed to respond effectively to light stimulation. It’s housed securely to view the flame directly, ensuring optimal performance in various environments.
Purchasing and Pricing Information
The Siemens QRA2 Photocell is a crucial component in industrial burners, ensuring flame presence and stability. It operates by detecting UV radiation from the flame, providing a signal to maintain burner operation. In the absence of a flame, the signal stops, causing the burner to shut down, thus preventing potential hazards such as gas leaks or explosions.
