The HS 1030 electromagnetic ultrasonic stress detector is a stress measurement technology based on orthogonally polarized transverse wave acoustic time difference. The greatest advantage is non-contact measurement. It does not require couplant and has no delay error caused by the coupling layer. It can realize more precise measurement of the transverse and longitudinal stress inside the material.
Performance Feature
→ Can detect residual stress and bolt tightening stress
→ 1GHz hard digital sampling frequency, sound-time measurement accuracy of 1ns, more accurate detection
→ Using electromagnetic ultrasonic technology, no grinding, no coupling, detection is more convenient
→ Residual stress value detection, bolt stress value detection
→ It is suitable for the detection of materials with coatings (paints, anti-corrosion layers) on the surface and is resistant to high temperatures
→ Dual-channel real-time display, the result is more clear
