Both the measurement light curtain and the detection light curtain are infrared light emitted by the illuminator, which is received by the light receiver to form a light curtain. So there is no difference, just the name is different, there are measurement gratings, detection gratings, etc.

Measuring light curtain or detecting light curtain is a special photoelectric sensor. It is used for detection and measurement in the fields of industry, machinery industry, production line, etc. It is the same as the principle of photoelectric grating sensor of safety grating. Technology industry.

It has been widely used in China and is mainly used in:
1. Freeway passage car separation system to achieve no-charge;
2·Automotive painting and other equipment, tracking shape, contour painting, saving paint, environmental protection, uniformity, etc.;
3. Logistics equipment, the contour of the object on the channel is measured in length, width and height, and the volume is calculated;
4. Production correction, high-precision detection and measurement, including precision correction, online and similar detection and measurement.

The measuring grating is divided into two parts, a transmitter and a receiver, and the outer shape is also relatively large. The detection light generated by the measuring light curtain emitter is not only a beam of light with the ordinary safety grating. It is an infrared scanning method, combined with the controller and its software, to realize the function of monitoring and measuring the external dimensions of the object, the controller Using software to program settings, you can communicate with the PLC or computer through the serial port connection, the software reads the scanned data.

This kind of detection light curtain detection light curtain has been widely used in foreign countries. With the exhibition of optoelectronic industry in China, more and more enterprises have already applied this field in general, and the market has great development potential. For the reform of traditional enterprises, Production efficiency, production accuracy have been greatly improved, saving personnel costs and labor, and the country's key development in the next 10 years to support high-tech industries.
