AGQ3.1A27 Siemens UV Amplifier

Overview

The Siemens AGQ3.1A27 is a specialized UV ancillary unit and signal amplifier designed for flame supervision in industrial and commercial burner systems. It is primarily used to interface ultraviolet (UV) flame detectors, such as the QRA series, with Siemens burner controls like the LME, LMO, LGB, and LGM series. The unit is a mandatory component in configurations requiring UV detection to ensure the flame signal is correctly conditioned and monitored for safety and reliability during burner operation.

Features

• Designed for ultraviolet flame supervision in conjunction with QRA… detectors
• Integrated signal amplifier to ensure clear communication with the burner control unit
• Compact housing design that allows for convenient mounting under the burner control’s plug-in base
• Mandatory safety component for specific Siemens burner control series
• High-quality German engineering ensuring durability and long-term performance in industrial environments
• Resistant to visible light and refractory glow to prevent false flame signals
