Abstract
In this paper, a sensing device specifically for measuring deformations of high temperature pipes is designed, and its applicability is verified both experimentally and theoretically. First, the design procedure and the working principle of the sensing device are described in detail. Then, experiments are carried out to prove the accuracy and the long-term stability of the sensing device. To verify the accuracy of the device, numerical simulation of the deformation of a pipe model is carried out using finite element method. Results from the experimental measurements are in good agreement with results from the numerical simulation. The long-term stability of the device is validated by monitoring the deformation. Conclusions are drawn that the designed sensing device has high accuracy and excellent stability and can be used for measuring deformations of high temperature pipes in power plants.
