Probe (Search Unit)

In ultrasonic testing, the probe contains the transducer, wedge, and damping materials. It converts electrical signals to ultrasonic waves and back. In eddy current testing, the probe (coil) generates the electromagnetic field. Probe design affects frequency response, beam characteristics, and defect detection capability. Proper probe selection and maintenance are essential for consistent, reliable NDT results.

Equipment Selection and Use

Proper selection and maintenance of probe (search unit) is critical for successful NDT inspections. Equipment must be calibrated and verified per applicable standards.

Maintenance and Verification

Regular maintenance and calibration verification ensure reliable equipment performance. Equipment that falls out of calibration can produce unreliable results.

Best Practices

• Always follow applicable NDT standards and procedures
• Use properly calibrated and maintained equipment
• Ensure personnel are properly trained and certified
• Document inspection procedures and results completely
• Keep current with industry standards and best practices
