The measuring light curtain is mainly used to detect the measuring object, such as the size, size, and compliance with the specified requirements. Measuring light curtain is a special photoelectric sensor. The main components of measuring light curtain are light emitter, light receiver and controller.

The measuring light curtain control principle is: the light emitter emits infrared light signals, which are directly received by the light receiver to form a protective light curtain. In a scanning mode, with the controller and software, the function of detecting and measuring the shape of the object is realized.
Measuring light curtain is widely used and can cover almost all detection and measurement fields, such as precision correction, online correction, centering correction, vehicle separation, object detection, shape measurement, small parts detection, object size detection, logistics sorting Volume measurement, component counting, toll station vehicle detection, vehicle over-limit inspection (length, width and height), channel passenger flow detection, object motion track detection, human body detection, security alarm, assembly line detection, automatic spraying, product counting detection, blanking Counting detection and so on.
