Although management and safety review are necessary, it is difficult to always measure the 3-axis displacement of structures such as pipes, and there is a problem of using expensive equipment.

In particular, the pipes installed in many industrial facilities are difficult to install a linear measuring device when measuring three-axis displacement due to the complicated installation shape and location, and the space is small, and the conventional displacement measuring magnetic sensor (LVDT) or laser method The surface temperature is high when fastening between the measuring device and the high-temperature structure is difficult to fasten directly, there is a problem that a separate heat dissipation device is required.
