Products Description
HS 900GW operates by utilizing the principles of the piezoelectric effect. It uses a specialized ultrasonic probe, designed in a contact-oriented manner with an angled wedge, harnesses ultrasonic oblique beams to generate guided waves within metallic elements. This configuration is particularly adept at swiftly assessing materials like tubes, rods, and plates.
Guided wave detection offers notable advantages, including its capacity for long-range signal transmission, exceptional accuracy in identifying targets, minimal signal degradation, impressive operational efficiency, and low cost.
Performance Feature
→ Portable integrated design, weight is only 2.3KG.
→ The piezoelectric transmission operates at a voltage of 800V with a tolerance of ±10%.
→ The newly introduced operational mode employs a simplified process, ensuring straightforward learning and user-friendly utilization.
→ The feature of multiple views display, denoted as A+B, enhances the visual representation of the image, providing a more intuitive understanding.
→ The special guided wave probe is used in combination with the pull-wire encoder, with good detection accuracy and high efficiency.
By coupling the specialized guided wave probe with the pull-wire encoder, impressive detection precision and operational efficiency can be acheived.
