The FBG Anchor (Bolt) Dynamometer AD-01 is made of constant elastic, high-strength, and corrosion-resistant materials. Two FBG strain gauges are installed on the annular elastic base to accurately measure the total amount of various load from bearing cables, anchors and bolts. The product has a built-in temperature compensation FBG, and the temperature compensation can realize temperature measurement at the same time. It is generally used in coal mines, tunnels, foundation pits and other civil environments that require protection and support. As a bolt force measuring gasket, it can be used for monitoring the fixing of wind turbine blades, real-time monitoring of the locking status of shield segments, and other environments for monitoring the fastening status of bolts.
