What is the working principle of measuring light curtain?

2022-11-15

Measuring light curtains are mainly used to detect objects' specification whether to meet the requirements, such as size. It is a special photoelectric sensor and consist of emitter, receiver and controller.


                  ESPE measurement light curtain

  

The control principle of the measuring light curtain: The emitter emits an infrared light signal which is directly received by the light receiver to form a protective light curtain. The protective light curtain can detect and measure the objects'  dimension with the controller and software in a scanning manner.


ESPE measurement light curtains are widely used and can cover almost all detection and measurement fields. Such as precision deviation correction, online deviation correction,centering deviation correction, vehicle separation, object detection, shape measurement, small parts detection, object dimension detection, volume measurement of logistics sorting, pasts counting, toll station vehicle detection, vehicle oversize inspection (length, width and height), channel passenger flow detection, object trajectory detection, human body detection, security alarm, production line detection, automation spraying, product count detection, blanking count detection and so on.


The performance characteristics of ESPE measuring light curtain: With highly sensitive detection and high accuracy, stable performance, it can resist magnetic interference, light interference, waterproof and dustproof as well as with strong shock resistance and self-check fault alarm function. Moreover, it also can be customized according to specific needs, such as used for personal protection, object size measurement and other purposes.
