Automatic measurement is possible! Unlike the method of installation inside the borehole, it can be done relatively cheaply.
The "DVP-100LA/DVP-100LB" is a subsidence gauge that can stably and automatically monitor ground subsidence and uplift. It can be used as a buried type without hindrance to measurements even when laid on its side. When installed in a concrete trough under a road, it does not obstruct the passage of vehicles or pedestrians on the surface. Additionally, maintenance can be performed at any time by using a concrete trough. 【Features】 ■ Does not obstruct the passage of vehicles or pedestrians on the surface ■ Less affected by sunlight and temperature, allowing for stable measurements ■ Relatively inexpensive compared to methods that involve installation in boreholes ■ Maintenance can be performed at any time by using a concrete trough ■ Capable of automatic measurement *For more details, please refer to the PDF materials or feel free to contact us.

Company information
We are professionals in "measuring," engaged in everything from sensor design and manufacturing to measurement services. We are a sensor manufacturer established in 1976, used to detect various behaviors such as rock mass movements, strain and internal stress within concrete, and the settlement and tilting of existing structures near construction sites, to ensure safety during construction and stability after completion when creating large structures like dams, tunnels, bridges, and skyscrapers. Our various sensors provide data confirming safety for Japan's representative structures, such as the Yokohama Bay Bridge, Landmark Tower, and Kansai International Airport, as well as urban underground infrastructure like subways and water supply and drainage systems, and hydropower plants, radioactive waste facilities, and underground storage facilities located hundreds of meters underground.
