The "SVD-1" is a sensor that measures strain using the principle of moiré patterns. It allows for a visual confirmation of the approximate strain value, and by analyzing digital images captured with a digital camera, it can obtain more accurate strain values. Additionally, its simple structure and lack of electrical components contribute to excellent long-term durability, making it suitable for long-term monitoring of social infrastructure. 【Features】 ■ No power supply required ■ Visualization of "strain" ■ Calculation of strain from digital images ■ Self-temperature compensation - Temperature compensation materials: concrete and mild steel *For more details, please refer to the PDF document or feel free to contact us.

The "EM Sensor" is a sensor technology that enables the direct measurement of stress (tension) occurring in rod-shaped steel materials (measured objects) such as cables and strands. It can be installed not only at the fixed end but also at any desired position. It can be installed and measured directly over the coating. Additionally, it has excellent long-term durability, allowing for long-term monitoring. 【Features】 ■ Measures direct stress, not strain ■ Easy to handle ■ Patent number No. 3942463 ■ Registered as a recommended technology for "technologies contributing to the longevity of public civil engineering facilities" in Hiroshima Prefecture, Registration No. 26-005-3 *For more details, please refer to the PDF materials or feel free to contact us.

This technology is a method for measuring the existing stress (strain) in concrete with high precision. It has received significant attention as a survey technology for the current condition investigation of PC bridges, and it was awarded the 18th National Land Technology Development Award. By using an optical full-field measurement method, it enables high-precision strain distribution measurements even in the micro-regions near the slit. 【Features】 - Measurement of the area around the slit before and after cutting using a line sensor scanner type full-field strain measurement device. - Inverse analysis using FEM analysis allows for the estimation of the existing stress in concrete members based on the measured released strain distribution. - In PC structures, it is possible to estimate the amount of prestress from the existing action stress. - It can also be utilized as data for the restoration design of PC bridges. *For more details, please download the PDF or contact us.

Using digital technologies such as 3D laser scanning, we support the repair and utilization of valuable cultural heritage structures, including stone walls. The 3D laser is a measuring instrument that can obtain extensive three-dimensional position coordinates and color information in a short time from a distance. Therefore, it allows for the rapid recording of the shapes and displacement measurements of large structures such as bridges and dams, as well as modern heritage sites. We also utilize high-resolution handheld scanners to create scaled models using 3D printers. 【Examples (excerpt)】 - Nogi Town Brick Kiln, Manda Pit → Shape recording, creation of general drawings → For detailed recording of damage conditions, aerial photogrammetry using a remote-controlled helicopter - Gunkanjima (listed on the World Heritage Tentative List) → Using 3D lasers and an omnidirectional panorama shooting system to record three-dimensional information of the reduced shape and collect images.

We clarified the characteristics of the camera through indoor experiments and developed a "mobile continuous image measurement system" that does not degrade image quality. This system can manage multiple industrial area cameras along a time axis and constructs a geometric correction system to create expanded images that maintain consistent image quality from camera images with different shooting resolutions, enabling the accurate creation of expanded images on curved surfaces and bent sections. We validated this system on monorail track girders and road tunnels, confirming that it allows for "clearer image acquisition" compared to conventional video cameras, and significantly reduces the number of days required for analysis in the post-processing stage. ● For more details, please download the catalog or contact us.

A fiber optic sensor is a measurement sensor that uses optical fibers, widely used in the measurement field not only for data communication but also as sensors for strain, vibration, temperature, and more. They can be categorized into several types based on their measurement principles, each having different characteristics. However, a common feature of all fiber optic sensors is their immunity to electrical noise and excellent durability. With the increasing importance of monitoring and diagnosing aging structures, fiber optic sensors have gained attention, and our company offers OSMOS sensors. ● For more details, please download the catalog or contact us.

The buried cultural property database "Yamato" consists of seven menus: site ledger, structural ledger, artifact ledger, image data, drawing data, original drawing data, and document data. Each database allows for data searching, printing, and more. In excavation surveys of sites, it is necessary to efficiently manage the vast amount of data, including artifacts unearthed during the investigation. Therefore, our company has developed a support system for centralized management of the obtained data as a database. By utilizing this system, we believe that it will lead to improvements in the efficiency of excavation surveys, enhancement of data management, and strengthening of research activities. ● For more details, please download the catalog or contact us.
