High Frequency Probe
High frequency probe refers to a single element transducer with a frequency higher than 20MHz, which includes HF contact probe, HF immersion probe and HF immersion self – focusing probe.
Specification and Model
Features
•Both contact probes and immersion probes have integrated delay lines, and self – focusing immersion probes do not have delay lines or lens
•The frequency range is 20 ~ 50MHz
•With broadband and narrow pulse performance, the probe has excellent near surface resolution and vertical and horizontal resolution
•A very small focal spot diameter in the near field or focus point
•Side mounted microdot connector for contact probe by default, and top mounted UHF interface for immersion probe and immersion selffocusing probe by default
Application
•Minor cracks on the surface
•High resolution detection effect is required, such as the ability to find small cracks or pores
•With the ideal surface condition, temperature and excitation setting, the thinnest thickness that 50MHz probe can reach in steel is 0.05 mm (0.0019 in) in thickness measurement mode
•Scanning acoustic microscope
