Siemens Combustion AGR450240650 U.V. Tube
The Siemens Combustion AGR450240650 U.V. Tube is a high-precision replacement phototube engineered for industrial and commercial flame monitoring. Designed as a critical sensing component for Siemens UV Flame Detectors, this tube detects ultraviolet radiation in the 190 to 270 nm spectral range. It is the primary replacement cell for several QRA series detectors, including the QRA2M, QRA10M, and QRA51M models. When integrated into the burner's flame safeguard system, the AGR450240650 converts UV light into a measurable electrical current, ensuring the burner control unit receives an accurate "flame-on" signal.
For veteran technicians, the Siemens AGR450240650 is a standard service part required to restore original sensitivity in combustion control systems. Prolonged exposure to high ambient temperatures or combustion byproducts can degrade UV cell response, leading to nuisance lockouts. This replacement ensures reliable pilot ignition proving and stable supervision of gas or oil flames. For high-temperature applications exceeding 50°C, we recommend ensuring adequate cooling air or using heat insulation glass to maintain the performance life of the quartz sensing element.
Key Benefits:
- Broad Compatibility: Direct OEM replacement for Siemens QRA2, QRA10, QRA53, and QRA55 series detectors.
- Fail-Safe Sensing: High spectral sensitivity to ultraviolet radiation (190-270 nm) prevents false flame signals from visible light or infrared sources.
- Rugged Construction: Built to withstand the harsh environments of industrial gas burners and commercial boilers.
- Efficient Troubleshooting: Restores signal strength to the flame safeguard, reducing downtime caused by weak or unstable flame detection.
Common Questions:
Which detectors use the AGR450240650 replacement tube?
This tube is technically designed for use in Siemens QRA2M, QRA10M.C, QRA51M, and QRA53/55 flame detectors.
What causes a UV tube to fail prematurely?
Exceeding ambient temperature limits (typically 50°C to 60°C depending on the detector housing) and exposure to excessive vibration are the leading causes of early UV sensor degradation.
Can I clean the AGR450240650 if the signal is low?
If the lens or the quartz tube itself is fouled with dust or oil, a gentle cleaning with a lint-free cloth and industrial alcohol may improve detection. However, if the internal gas or electrodes have aged, the U.V. Tube must be replaced to ensure system safety.
