Over 20 years of domestic experience in tunnel interior displacement measurement using laser distance sensors.
It is often seen that 2 to 3 laser distance sensors are used for measuring internal tunnel displacement. We highly recommend using high-precision, compact, and lightweight sensors.
By using two or three laser distance sensors, a system can be constructed for measuring internal displacement in tunnels. It is very user-friendly due to its high precision (±1mm@2σ), compact size, and lightweight (350g), making system construction easy. The measurement distance can reach up to 100m (or 500m when using a reflector), making it suitable for most tunnel environments. We offer two types of measurement temperature ranges: -10℃ and -40℃, making it compatible for measurements in Hokkaido. The waterproof rating is IP65. If necessary, an external cover can be applied for use. Our company provides comprehensive support for usage, implementation, control software development, and technical assistance. If you have any concerns, please feel free to contact us. 【Features】 ■ High-speed measurement achieving 250Hz ■ 100m measurement (500m with dedicated reflector) ■ Compact and lightweight at 350g (140x78x48mm) ■ Measurement temperature range -40℃ to +60℃ ■ Compatible with various interfaces (PROFINET/EtherNet/EtherCAT) *For more details, please refer to the PDF document or feel free to contact us.

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.
