General Description

True to the tradition of weber Sensors, the laser-captor high performance laser barrier system offers product detection whic can be relied on in the harshest of all Steel Industry environments.

Where heat, steam, water, dust and smoke preclude the use of conventional detection systems, the laser-captor's rugged design ensures maintenance free operation and longevity, together with a dependable high performance operation.

At furnace temperatures in excess of 2400 F (1315 C) the laser-captor is used extensively in the tracking of slabs and billets through pusher and walking beam furnaces. Other common applications include: anti-collision detection, safety barriers, accurate positioning and through beam barrier detection.

At the heart of the laser-captor transmitter unit is a high-tech IR semiconductor laser element, that is accompanied by electronics and collimating lens system, All are totally encapsulated and housed in stainless steel. In the receiver unit the highly sensitive photo detection system and output electronics are protected from the environment with the same rugged design.

On site adjustment of receiver's output signal response time between 16ms and 1s is possible by means of a potentiometer. This allows for specific applications, to find the best balance between a response time and the incidence of short term false signals.

Also available is a receiver unit with an additional control output. This output is activated when the received signal strength falls below a field-adjustable threshold, indicating reduced signal reception and the possibility of false signals on the main output due to i.e. dirty lens covers.
