Immersion Probe

介绍 Features&Applications Specification and Model

Immersion Probe -North American Standard

Immersion Probe

Probe is design for total or partial immersion into water or other liquids to create ultrasonic beams.

Features&Applications

Features

· Strong Pressure and Corrosion Resistance

· Excellent Acoustic Impedance in Water or other Liquids, 1/4 wavelength of matching layer can ensure maximum power outputs

· No Coupling Issues between Probe and Liquid

· Acoustic Beam can perform Spherical Focusing (F) or Line Focusing (CF), to increase ability of defect identifications

· Three types of performance probes can meet most of detection needs

· PL - Universal Series

· PH - Short Pulsing Series

· C - Composite Series

Applications

· Unfocused probes (planar) are used for general applications and penetrating thicker materials

· Point focused probe (spherical surface) is generally used to improve the sensitivity and signal-to-noise ratio of small flaw defection

· Line focused probe (cylindrical surface) is generally used for the detection of pipes and bars

· Online thickness measurement; Automatic scanning; Material analysis; Imaging system

Specification and Model

Instruction：

1. Most water immersion probes working between - 10 ~ 55 ° C (14 ~ 131 ° f). If the temperature exceeds the limit, peeling will occur between components, resulting in permanent damage to the probe. Limit working temperature (customized) can reach -55 ~ 120 ° C (- 67 ~ 248 ° f).

2. Transducers should not be submerged for periods exceeding 8 hours. Allow 16 hours of dry time to ensure the life of the unit.

3. The focusing distance of the unfocused probe is about equal to its near-field length. Since the last maximum amplitude of the probe occurs at a distance equivalent to the near-field length, all probes cannot focus when it is greater than the near-field length.

4. At a given frequency and element size, the focal length of the probe is limited. The actual maximum amplitude of unfocused probe is about 0.6 times of the near-field length, and that of point focused probe is about 0.8 times of the near-field length, for line focused probe max amplitude may not correspond tothe nominal focusing. When the focus probe exceeds the above maximum but less than the near-field length, the increased sensitivity at the focus is not obvious.

5. For the problem of the long focus length transducer has a large offset in the center frequency near the focus point, please refer to the description on the probe test report.
