The piping system of fossil power plant is subject to a severe thermal range and usually operates well into the creep range. Cyclic operation of the plant subjects the piping system to mechanical and thermal fatigue mechanisms and poor or defective support assemblies can impose massive loads onto the system. In order to prevent the serious damage and failure of the critical pipe system in fossil power plants, 3-dimensional displacement measurement system was developed for the on-line monitoring. Two types displacement measurement systems were developed with LVDT type sensor and rotary encoder type sensors. These systems were installed and operated on the piping system of fossil power plant successfully.
