Subsurface multi-segment displacement / stratified settlement measurement! Multi-point displacement gauge compatible with casing.
The "PM-100G-□, PM-100GB-□" is a multipoint displacement gauge used for multi-stage rock displacement measurement in large underground cavities such as underground power plants, as well as in large slopes associated with dam and road construction. It consists of a conversion unit that converts displacement into an electrical signal, an anchor unit that is fixed multi-stage within a borehole, and a wire unit that transmits the displacement of the anchor unit to the conversion unit, allowing for the installation of six anchor points in a φ66mm borehole. The conversion unit is detachable and compatible with casing drilling. 【Features】 ■ Casing compatible ■ Low sliding resistance in the sensor unit, allowing for smooth detection movement ■ The tension of the PM-100GB-□ sensor unit is approximately five times that of the PM-100G-□ *For more details, please refer to the PDF document 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.
