There are many cases where laser distance sensors are used for measuring bridge deflection. We highly recommend using high-precision, compact, and lightweight sensors.
Features - A system for dynamically measuring instantaneous values during vehicle operation, as well as the deflection of railway bridges and heavily trafficked bridge girders. - Installed directly beneath or diagonally below the girder, it continuously measures the distance to the girder during vehicle passage to calculate and output the deflection amount. - A significant advantage is that installation is easy and non-contact laser distance meters can be utilized, eliminating the need for extensive preparations or traffic regulations. - If the target object is black and insufficient reflected light is obtained, reflective stickers or similar materials can be used. - There is a proven track record of use for both long-term and short-term applications on steel bridges, concrete bridges, roads, and railways. - If the displacement exceeds the management value, a rotating light will issue a real-time alarm, allowing for decisions such as temporary work suspension. Our company provides comprehensive support for usage, installation, control software development, and technical assistance.

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.
