Description The tunnel lining concrete is a structure connected to each span, and deformation occurs depending on the surrounding conditions. In particular, the joint part for application is where the deformation is caused and the displacement occurs in each direction (radius, tangential and axial direction). ▣ Applications Composition & CharacteristicsRead More →
Description The Electric Joint Meter is used to measure the size change of the surface, connection parts, and cracks in concrete structures. A high-precision and linear potentiometer is mounted inside the housing, allowing the rod to push or pull the sensor when deformation occurs. The movement is then transmitted toRead More →
Description The Electric Crack Meter is used to measure the size change of the surface or connection part, as well as cracks in concrete structures. A high-precision and linear potentiometer is mounted inside the housing. When deformation occurs, the rod pushes or pulls the sensor, which sends the movement toRead More →
Description The Digital Settlement Meter is designed to measure the set point and the settlement of the target ground or structure by means of the head difference (pressure change), and it calculates accurate values at high resolution. ▣ Applications ① Measurement of settlement of flimsy ground and embankment ② MeasurementRead More →
