Kromschroder Quartz glass disc with seals 74960612

This sensor component is a quartz glass disc supplied with gaskets for Kromschroder UVS flame monitoring sensors. The disc is made of quartz glass, offering high transparency to ultraviolet radiation. It also provides high thermal resistance and mechanical strength to withstand harsh combustion environments. The included gaskets ensure a sealed fit, protecting the sensor from contamination and combustion products.

Parts of this type are selected by the dimensions of the disc (outer diameter and thickness) and the sealing arrangement, both of which must match the detector housing. When replacing the disc, inspect the seating surface for soot or damage, and fit the new seals snugly to maintain a gas-tight joint.

A cracked or heavily fouled disc will attenuate the ultraviolet signal, causing a flame-failure lockout. Check the disc for cracks, soot, or other deposits that could obscure the sensor.
