The Tension Stress Detector consists of a program-controlled host unit and an operation front-end. The front-end includes measurement and control circuitry, a numerically controlled pump station, a dedicated hydraulic jack, load sensors, and other components. It employs the re-tensioning method principle to test individual steel strands. The system is now widely used in Zhejiang, Yunnan, Guangdong, Guizhou, Anhui, Guangxi, and other provinces.
