The measurement technology of HS 1020 ultrasonic bolt stress detector is developed based on the theory of acoustic elasticity. The system software has high measurement accuracy, friendly interface, simple operation, the hardware system has a high degree of integration, compact size, and easy to carry.
It can be widely used in the measurement tasks of the bolt axial stress of a variety of bolted connection structures, such as installation site inspection, in-service inspection, online monitoring and other construction processes in aerospace, bridge construction, wind power, thermal power, hydropower, petrochemical and other industrial fields.
→ The detection speed of the instrument is fast, and the probe can be directly read by placing on the end of the bolt
→ Flexible in use, the ultrasonic equipment is small, portable, and energy-saving. It can work for a long time relying on a portable and small-capacity power supply, which allows engineers to conveniently take to the construction site for inspection
→ The direct reading of the comtrast value between the sound velocity difference and the standard model caused by the internal stress change of the bolt has high accuracy
