AI Technical Summary
Existing vibrating wire strain gauges suffer from insufficient accuracy, unstable data transmission, and poor adaptability to operating temperatures in long-term monitoring of concrete components, which affects the safety monitoring of concrete components.
A triaxial strain monitoring device for concrete components was designed. It is composed of x, y, and z axial strain vibrating wires, combined with electromagnetic coils and data storage and transmission modules to realize multiaxial measurement and wireless data transmission. It uses a high-strength stainless steel shell to adapt to a temperature range of -40℃ to +80℃, and is equipped with backup data and power interfaces to improve reliability.
It achieves high-precision, wide-range strain monitoring with a measurement error of less than 0.3%. The automatic data acquisition and transmission are reliable, making it suitable for long-term monitoring of different concrete components, reducing the human error rate, and expanding the working temperature range.
