Ultrasonic Thickness Gauges
How to Choose the Right Ultrasonic Wall Thickness Gauge
Ultrasonic wall thickness gauges are used for non-destructive measurements from a single side and are available in various types depending on the application, material, surface condition, and required precision.
Dual Element Probe Gauges
These gauges use transducers with two crystals—one to send the ultrasonic signal and another to receive it. They are ideal for corroded, pitted, or uneven surfaces and can measure wall thicknesses as thin as 0.6 mm depending on the model and probe used.
- TI-25 Series: Ranges from the basic TI-25M for steel to the TI-25DLXT with through-coating measurement and data logging.
- TI-MMX & TI-MVX Series: Advanced features such as B-Scan, Scan-Bar, and A-Scan (TI-MVX only) for comprehensive analysis.
- TI-CMX Series: Offers similar capabilities to the MMX models, with the added ability to measure both wall and coating thickness separately using dual velocity settings. Models include B-Scan, A-Scan and full-colour options.
Specialty Automotive Gauges
Designed for engine builders and race shops, these dual element gauges measure cylinder walls, chassis tubes, body panels, and other automotive components. They are ideal for mapping material integrity and assessing components for reuse or replacement.
- PR-9 Sonic Tester: Pulse-Echo gauge designed for measuring and mapping various materials and surfaces in race shops.
- PR-8V: Builds on the PR-9 by adding Echo-Echo and B-Scan functionality for deeper analysis.
Single Element Probe Gauges
- Precision Gauges: These models use delay-line transducers (acrylic, epoxy, or graphite) to separate emitted and received signals, enhancing resolution and minimising surface noise. Ideal for measuring thin materials and detecting near-surface flaws with high accuracy.
- TI-007X Series: Precision thickness measurement from 0.15 mm with a resolution of 0.001 mm. Available with and without data logging.
- TI-PVX: Utilises pencil probes or standard delay-line probes with A-Scan and B-Scan capability. Ideal for small curved areas or specialised surfaces such as copper rails in automated systems.
- High Penetration Gauges: These models use direct-contact single-element probes for materials that are difficult to inspect due to coarse grain structures or low acoustic transmission, such as castings, rubber, fiberglass, FRP, carbon fibre or lead.
- HPX-DLP: Offers frequency options from 0.5 to 10 MHz and is equipped with the tools needed to inspect materials that other gauges struggle with.
