The length dimension is the benchmark of all geometric dimension measurements. In the length measurement domain above 6 meters, China has always been at the level of low measurement accuracy, poor stability, complex operation and low degree of digitalization; Based on the demand of Industry 4.0 and the improvement of domestic measurement technology, it is urgent to independently develop ultra long and high-precision length measurement equipment, which can be used for the traceability calibration of large-scale measuring tools and gauges for large-scale equipment manufacturing in aerospace, shipbuilding, mechanical heavy industry and other fields.

At the site of the length precision laboratory of a metrology institute, a high-precision laser length measuring machine developed by Shenzhen Zhongtu Instrument was erected in the center of the laboratory. The model of the instrument is SJ5180-10000, its effective measurement size is 10 meters, and the overall length is nearly 12 meters. The instrument is an ultra long laser length measuring machine, which needs to be assembled, debugged and accepted on site. The length measuring machine has been installed and debugged on site, and the accuracy function acceptance of the equipment has been carried out. The index is better than the design index ±（0.7+L/1000）μm（L，mm）； The actual measurement accuracy of the instrument reaches ±（0.5+L/2000）μm（L，mm）。

For the laser length measuring machine with a length of 10 meters and an accuracy design index of 0.7 μ m, the researchers of Shenzhen Zhongtu Instrument were also in the heart at the beginning; Although it has been comprehensively considered in the design, there are too many factors affecting the accuracy on site, such as marble grinding flatness, guide rail installation straightness, foundation stability, on-site vibration, temperature change, laser stability, etc. Any unstable factor may cause the accuracy to fail to reach the design index.

The resolution of the 10m super length measuring machine should reach 0.0001mm The measurement indication error within the full length shall be within ±（0.7+L/1000）μm This is also an unprecedented challenge for the on-site assembly and adjustment technicians of China Library. They worked hard and worked overtime to debug and correct the equipment again and again. Through hard work, the installation and commissioning of the instrument was finally completed. All indicators and functions met the technical conditions for acceptance signed by both parties, and passed the formal acceptance of the customer.

China Library Instrument has been working silently in the field of geometric measurement instruments for more than ten years. In recent years, China Library Instrument has launched the industry 4.0 intelligent manufacturing measurement domain, and has successively developed a large number of measurement products, such as laser interferometer, white light interferometer, intelligent thread profiler, image measuring instrument, laser tracker, coordinate measuring instrument, confocal microscope, step meter, etc., providing customers with intelligent measurement solutions, It has been widely praised and praised by customers. In 2021, China Library Instrument was awarded the title of "Jingte New Little Giant" by the Ministry of Industry and Information Technology.

In the future, we are confident to do research and development of instruments and equipment with longer size and larger measurement range for customers, modernize and intelligentize traditional and classic instruments, provide customers with better software and better service, and promote the high-quality development of domestic instruments.
