Siemens UV Spare Cell Bulb AGR450 Series

Siemens AGR450 Series UV Replacement Cells for QRA Flame Detectors

Siemens AGR450 Series UV Spare Cells / Bulbs are replacement ultraviolet sensing components developed for selected Siemens QRA Series flame detectors. They detect UV radiation produced by burner flames, supporting flame presence monitoring through the connected burner control system.

Key Features

• Replacement ultraviolet sensing element for compatible Siemens flame detectors
• Responds to UV radiation emitted during burner flame combustion
• Available for selected Siemens QRA2, QRA10, QRA5 and QRA7 detector models
• Intended to replace the internal UV sensing cell in suitable detector assemblies
• Used in industrial burner and boiler flame monitoring applications

Industrial Applications

Siemens AGR450 UV replacement cells are used when servicing compatible flame detection equipment installed on industrial burners, boiler combustion systems, furnaces and gas-fired heating equipment equipped with Siemens QRA flame detectors.

Selection and Replacement Instructions

Before purchasing a replacement UV cell, confirm the complete flame detector model and the required spare part number. Different QRA detector versions may use different sensing cells. Replacement must be carried out by qualified technicians following Siemens instructions. After installation, the flame detection response and associated burner safety functions must be checked before returning the equipment to service.
