Accuracy ±1mm, with a proven track record in monitoring measurements for bridge maintenance work.
During the bridge repair work, monitoring of deflection and other factors is conducted using a laser distance sensor throughout the construction period (several years).
The social infrastructure that supports our daily lives. Infrastructure facilities support our lives, contribute to the revitalization of communities, and enrich our lives. On the other hand, deterioration is progressing in areas that are not visible to us, which could lead to major accidents. Large structures such as bridges and tunnels. Until now, inspections have been managed through methods such as visual checks or tapping sounds, but we are facing a situation of a shortage of technicians for maintenance and management, as well as financial constraints. Sensors from our company have been installed on a certain bridge, utilizing communication devices to quickly grasp the condition of the structure and employing sensor monitoring technology to prevent major accidents such as collapses. This bridge spans a major road and regularly monitors the changes in deflection caused by the vibrations from passing cars and large trucks. The "D-series" is a high-precision laser distance sensor that achieves high-speed measurement at 250Hz. Our product complies with IP65 and can measure in environments ranging from -40°C to +60°C. Our company provides comprehensive technical support, including usage instructions, implementation, development of control software, and post-installation support.

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.
