Safety light curtain principle

Principle introduction: The measurement light curtain is a special photoelectric sensor. Like the ordinary through-beam photoelectric sensor, it consists of two parts: a transmitter and a receiver that are separated and placed opposite each other. However, its appearance is larger and long tube-shaped. The detection light generated by the measurement light curtain emitter is not just one beam like an ordinary sensor, but an array of light is generated at regular intervals along the length direction to form a light curtain, which can be monitored in a scanning manner in conjunction with the controller and its software. and the function of measuring the dimensions of objects.
In order for the light curtain measurement system to work properly, it needs to be equipped with a controller. The controller is programmed using software and can provide a variety of scanning modes and detection and analysis modes. It can also communicate with a computer through a serial port connection to transfer control. or scan results, and trigger signals can also be connected to control the scanning process.
The series of measurement light curtains are suitable for high-precision detection and measurement
Including online detection precision correction hole detection and similar detection and measurement above. Each system includes a pair of high-resolution light curtains and two cables, and the output method includes communication switch analog high and low levels.

The composition of the measurement light curtain
It is composed of a transmitter and a receiver. The distance between each two beams is called the optical axis spacing. The optical axis spacing of the series measurement gratings is equal
