In the field of precision manufacturing, the micrometer level difference in material thickness often determines the reliability of the product. The third-generation single crystal ultrasonic thickness gauge PM5 Gen3 developed by Shenyang YUSHI Instruments has successfully achieved precise differentiation of steel blocks ranging from 0.996mm to 1.003mm with a resolution of 0.001mm. Its technological breakthrough and application value deserve further exploration.
Precision Calculation of Ultrasound Waves and Time
Taking the measurement of 0.996mm and 1.003mm steel blocks as an example, the time difference between the two is only: (1.003-0.996) × 2/5929 ≈ 2.36 nanoseconds. This precision requires the equipment to have:
1. Nanosecond time resolution: The PM5 Gen3 uses a high-speed chip with a high-frequency sampling rate to ensure the capture of nanosecond level time differences
2. Intelligent gain control: By adjusting multiple levels of gain (as shown in the interface in the figure), the signal strength is optimized to make weak echoes clear and distinguishable (the gain can be manually or automatically adjusted)
3. Multiple probe parameter configuration: Built in multiple sensors to correct sound velocity parameters, ensuring adaptability to single crystal probes such as delay block probes, contact probes, protective film probes, pen probes, water immersion probes, etc.
Industrial Application: The Quality Revolution
PM5 Gen3 has become a key tool for quality control in fields such as aerospace, petrochemicals, and automotive manufacturing.
1. Aircraft engine blades: The thickness tolerance of turbine blades should be controlled within ± 0.015mm, as exceeding this limit may result in centrifugal stress failure. After using this equipment, the blade detection efficiency of a certain aviation enterprise increased by 300%
2. Oil and gas pipeline inspection: If the corrosion thinning exceeds a certain thickness, it needs to be repaired or replaced. PM5 Gen3 can provide early warning of hidden dangers. The application of a pipeline project by PetroChina shows that the deviation between equipment testing data and laboratory results is ≤ 0.003mm
