Application Specific Transducers

Sonatest are capable of manufacturing a wide range of transducers to suit any application. If you cannot find the appropriate transducer within our range, Sonatest will develop a “Special” transducer specifically for your application requirements. Over the last 40 years Sonatest have manufactured Special Transducers for many different applications ranging from the rail industry to the aerospace industries.

Examples of some of the "Specials" which we have previously developed:

The Rail Probe
One example of our capabilities with “Specials” is the Rail Probe. The Rail Probe was specifically designed to have two angle probes (2MHz, 70°) at either end and a compression probe in the middle (2MHz). This probe is used in combination with a flaw detector on a railcart to scan rails. The Rail Probe has proved to be a very successful transducer which is manufactured today exclusively by Sonatest.

Boiler Tube Probes (BTPs)
Small low profile twin angle beam transducers with integral cables for the inspection of welds in steam boilers in power stations. Axially radiused to suit 50mm boiler tubes. 5MHz, with an increased toe in angle to produce a short focal length to suit these welds and available as 70° and 60° with BNC or LEMO 1 connectors to fit flaw detectors.

Asia Single Angle Range
A high specification transducer with high signal to noise ratio and a very small dead zone. Employs a lead zirconate 10 x10 crystal, with the standard Japanese reference number engraved on the side of the brass/nickel plated casing—5C10x10A70L. Also has an engraved scale. The index point is 10 mm from the front edge with an angle tolerance of >69º <70º. Connectors are Mini Lemo 00 or G-Plug. Part No: ASA5-70ZT or GT. Also at available 45º and 60º.

Soft Tipped Probes (STPs)
Soft Tipped transducers, are for use with Sonatest dry contact flaw detectors, such as the Dryscan 410D, and the Masterscan Series. Applications include the testing of composites, rubber, wood, ceramics and friction material. No surface preparation is required for the majority of applications. Ideally suited for test specimens with complex shapes. Operating in through transmission mode using two transducers.

Roller Probes
Dry contact roller probes are mainly used where automated testing is required and can also be used with the Dryscan 410D. Roller probes have miniature BNC connectors.

If there is not a transducer here that suits your application, we can build one that will be. Please contact usfor further assistance.
