Measurement of the cross-section inside the Seikan Tunnel using Dimetix laser distance sensors.
In early December 2022, under the supervision of the Railway and Transport Agency and the Railway Technical Research Institute, a joint measurement of the cross-section of the Seikan Tunnel was conducted with JR East Engineering.
The setting is within a point group interval of 10 mm, and measurements were taken at a total of four cross-sections (a total of 33 side lines). The reason for using the Dimetix laser distance sensor in this measurement is as follows: 1) Measurement accuracy is within ±1 mm. 2) It has an insulated structure that does not short-circuit the track. 3) It operates on a rechargeable battery. 4) It is easily portable by hand. Our company provides comprehensive technical support, including usage instructions, installation, control software development, and post-installation support. If you have any concerns, please feel free to contact us. [Features] ■ High-speed measurement achieving 250 Hz ■ 100 m measurement (500 m when using a dedicated reflector) ■ Compact and lightweight at 350 g (140 x 78 x 48 mm) ■ Operating temperature range -40°C to +60°C ■ Compatible with various interfaces (PROFINET/EtherNet/EtherCAT) *For more details, please refer to the PDF document or feel free to contact us. *The old series of our non-contact laser distance sensors (DLS-C FLS-C series) has been discontinued as stock has run out.

Company information
Since its establishment, we have been involved in the development of our own products, starting from gathering ideas, and have repeated the processes of mechanical design, processing, circuit design, and embedded programming every year. Currently, we are engaged in both OEM production and the sale of our own products, and we intend to continue developing measuring instruments that can further meet our customers' needs. We are also the general agent for Dimetix in Switzerland and are focusing on the sales of red laser distance meters. This product has been adopted for measuring the height of the Tokyo Skytree, the tallest structure in the world. We believe there are still many applications for this technology, and we would like to explore each one. In recent years, we have also been focusing on measuring instruments for railway-related construction limits. We have started to receive inquiries from East Japan Railway Company regarding the development of measuring instruments for construction limits in various fields such as construction, civil engineering, signaling, and power. Additionally, we received an Encouragement Award at the 28th Ota City Small and Medium Enterprises New Products and New Technologies Competition for our graphic-integrated construction limit measuring instrument.
