F Finger Tip Contact Transducers
Model F are small diameter transducers with side-mounted Microdot connectors. GP Series* offer the best combination of sensitivity and resolution for most applications. HR Series* are highly damped for applications where high resolution is required. C Series* have piezocomposite elements and offer superior penetration in highly-attenuative materials. All Model F transducers feature an ergonomic design for improved operator control and comfort.
Single-element contact transducers are longitudinal-wave (straight-beam) transducers designed for general-purpose manual ultrasonic inspection where test materials are relatively flat and smooth. They provide high sensitivity for better penetration, small-flaw detection, and have abrasion-resistant wear plates for extended service life. Typically used with Ultrasonic Flaw Detectors, that are Calibrated with Blocks.
Typical Applications
- Flat Plates
- Bars & Pipes
- Thick-Section Parts
- Tanks
- Objects with simple and non-complex geometries
Key Benefits
- Smaller diameter allows for inspection of pipes, bars, and tubes
- Abrasion-resistant wear plates for extended service life
- Effective in small-flaw detection
Series
*GP Series – General Purpose series of transducers are recommended for most applications and have a good trade-off between sensitivity and resolution. They have a medium frequency bandwidth of 40-65% at -6db but with more ring-down cycles in the waveform.
*HR Series – High Resolution series of transducers are highly damped and recommended for applications where enhanced axial and near-surface resolution are more important. Generally includes thickness measurement and near-surface flaw detection. HR series have less sensitivity and the GP or C series with -6db frequency bandwidth of 50-100% range.
*C Series – Composite (Piezocomposite) series of transducers have superior sensitivity and penetration, especially in highly-attenuative materials. C Series have both higher resolution, sensitivity, and have wide bandwidth (60-120% at -6db) due to the lower acoustic impedance of the material. They couple more efficiently into plastic wedges, delay lines, and water.
