weberfoto-captor The remarkable foto-captor is the leading hot product sensor throughout the world's steel industry. Its highly advanced infrared radiation technology and design concept serve sophisticated industrial systems in metal manufacturing, heat treatment and glass making. With more than 25 years of experience, our foto-captors are produced for tough, demanding industries and guaranteed by our commitment to supply high accuracy, long-life reliability and dependable performance with each one of our maintenance-free sensors, even in the harshest environments. Well respected throughout the industry as problem solvers in infrared detection, we developed a wide range of foto-captor types with various response temperatures, remote lens systems, fibre optic cables, cooling jackets, air purges and other smart accessories to accommodate many different applications in hot product detection. The foto-captors are compensated for high ambient temperatures and don't require adjustment. The highly selective viewing fields and temperature set-points prevent signaling outside these parameters. Because your environment is our home, we are devoted to the continuing development of user-oriented infrared sensors for process control and are proud to be unsurpassed. This, however, was only possible as a result of the vigorous co-operation with a wide range of respected customers. Our customers requirements keep our research and development abreast and provide the stimuli for the future.

The foto-captor. hot metal detector, is an infrared switch especially designed for fault-free operation in the harsh environments of heavy industry. For more than 25 years foto-captors have been successfully installed to monitor hot products in: • Rolling mills to control cut to length shearing, monitor hot rods, controlling roller tables, coil regulating, switching in crosscut hauler, monitor de-scaler, cooling beds, winder control, monitor edge washing, continuous casting or tracking of high speed wire. • Coke ovens to monitor quenching, cutting off press, monitoring exhaust gas flare and conveyors...

• Interchangeable Lens and Fibre Optic Cable (FOC) • Remote mounting of electronics Design Features The use of fibre optic cables enables mounting of the electronic unit at a distance from the high temperature area. This has the advantage of allowing detection of IR-radiation of hot material from close range. The following design variations are available for such cases: Fibre Optic Cable (FOC) Other lengths on request. Response temp, with IR-FOC increases by 30 °C/m for lengths greater than 2 m. Remote Lens No Variant Ambient temp. 1 Lens in standard housing max. + 85 °C 2 Lens in special housing...
