fiber optic technology for flame scanner

Functional description

When all solutions for mounting a sensor on the side glass of a combustion chamber go to fail, there is another solution for scanning the flame by the “Fiber Optic Cable”. Minimum space occupation and high temperature resistance side by very high vibration tolerance are the most important advantages of the fiber optic cable, in this application.

The “Fiber Optic Cable” can be used in the length from a fraction of a meter to ten meters and the suitable number of elements. Both ends of “Fiber Optic Cable” can be joined to any mechanical connection, by varied head screw types. Also, for different light spectrum of flames, there is two type of lens to apply. There is a specification table of standard optical fiber as below:
