The Working Principle and Application of Measurement Light Curtains

The Working Principle of Measurement Light Curtains

  Measuring light curtains usually consist of a pair of transmitters and receivers. The transmitter emits a beam of infrared or visible light, and the receiver is used to receive the reflected light. When an object enters the beam, it blocks some of the light, causing a change in the light intensity received by the receiver. By monitoring the change in light intensity, the controller of the measuring light curtain can determine the position and movement of the object.

The Application of Measurement Light Curtains

1. Industrial safety: ESPE measuring light curtains are widely used in robots and automated production lines to protect workers from dangers such as clamping and impact. When a person approaches a dangerous area, the measuring light curtain can quickly detect it and stop the movement of the robot or production line to ensure the safety of the work scene.

2. Position detection and navigation: Measuring light curtains can be used for position detection and navigation in robot applications. By setting multiple light curtains or using reflectors for reflection, the light curtain can be constructed as a reference grid, thereby achieving high-precision measurement and navigation of the robot's position and direction.

3. Object size measurement: In the automated production line, the measuring light curtain can be used to measure the length, width and height of the object. By detecting the blocked area of the object on the light curtain, precise size measurement and quality control can be achieved, improving the efficiency of the production line.

4. Personnel counting and flow control: Measuring light curtains can be used for personnel counting and flow control, especially in public places, shopping malls, and stations where personnel management is required. By detecting the time and frequency of personnel entering and exiting the light curtain area, accurate personnel counting and flow statistics can be achieved.

   
   

   
   

   ESPE measuring light curtains, as a safety device, based on the working principle of optical sensors, can efficiently and accurately detect the position and movement of objects, ensuring the safety of the work area. In addition to safety, measuring light curtains also play an important role in areas such as robot navigation, object measurement, and personnel management. With the continuous development of technology, the application of ESPE measuring light curtains in more fields will continue to expand, providing better solutions for industrial safety and automation.
