laser barriers HLS series laser barriers
 

 

Principle :

The EUROLASE laser barriers have been designed for applications requesting a long distance detection and in stringent environments (dusts, flames, fog, rain, snow).

 

The system is composed of 2 separated modules (transmitter and receiver), that have to be installed one in front the other one. The transmitter generates an infrared pulsed beam (invisible). If a moveable object or product crosses, the beam is cut. This will be detected by the receiver.

 

The transmitter is available in standard or cooled version, and it will be associated to a receiver corresponding to the output required type, (commutation frequency, sensibility threshold, …).

 
 

Applications :

  • Detection of oversized vehicles at tunnel entry side

  • Long ranges safety barriers

  • Detection of hot products inside furnaces, with no interference of the flames

  • Detection of products breakage on line

  • Protection of ships masts

  • Cutting check on continuous casting machine

  • Continuous traveling products counting (bars, bottles of glass, tubes, …)
