Tunnel cross-section automatic measurement with 'Architectural Clearance Measuring Device' LDM300A
This is a building gauge measuring device for railway operators. It can automatically measure tunnel cross-sections. Equipped with a color LCD, it allows for on-site verification of measurement results.
This is a building gauge measurement device for railway operators. Its main purpose is to be used in railway facilities such as tunnels, platforms, and signals. It controls the rotation angle of the internal laser distance sensor with an internal motor to perform continuous and single measurements. The measurement results are saved to a microSD card, allowing for serial data communication output to a PC or similar devices. A dedicated base is used to install the measuring device on the track, and it can simultaneously measure cant and slack along with the building gauge measurement. To measure, the base is installed on the rail, and the laser is directed to the desired measurement point, followed by pressing the measurement switch. The horizontal distance from the rail surface and the track center, as well as the height, are measured, and at the same time, the measurement point is plotted on the building gauge diagram, and the clearance value is calculated. 【Features】 ■ Equipped with a color graphic LCD - Allows for confirmation of measurement results on-site ■ Equipped with an inclination sensor - Cant measurement is possible with the dedicated base ■ Compact and labor-saving - Has a widening measurement function *If you are interested in rental, please indicate your rental request by clicking the "Contact Us" button below.

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.
