Kromschroder Quartz glass lens with seal 74960611

This sensor component is a quartz glass converging lens supplied with a sealing gasket for the Kromschroder UVS10 flame detector. It is made of quartz glass and weighs 0.024 g. The lens is intended for use in industrial burners, furnaces, and heat generators. Its spherical shape converges flame ultraviolet radiation, and the included seal closes the detector optical path. Compared with a flat window, this lens increases the achievable flame observation distance.

For this type of component, selection is based on compatibility with the detector model and the mounting arrangement. The replacement gasket must seat snugly to maintain a gas-tight seal against the detector body. Before fitting, inspect the old lens for damage and verify the optical path is clear. A new seal should always be fitted at the same time; do not reuse a compressed or hardened seal.

A contaminated, cracked or thermally stressed lens of this type transmits less ultraviolet radiation. The burner may then run unevenly or shut down because the control does not confirm flame. In some cases the detector will not respond at all. Check the lens for soot, crazing or thermal stress marks, and clean the detector window during inspection.
