AGG02 Siemens Heat Insulating Lens

Overview

The Siemens AGG02 is a heat-insulating glass kit designed to protect ultraviolet (UV) flame detectors from high temperatures in industrial and commercial burner applications. Specifically engineered for use with Siemens QRA series flame detectors, such as the QRA2, QRA4, and QRA10, this insulating lens extends the service life of the UV cell by providing a thermal barrier against radiant heat. It is a critical accessory for maintaining the reliability of flame supervision systems in high-heat environments.
