Sonatest are capable of manufacturing a wide range of transducers to suit any application. If you cannot find the appropriate transducer in the catalogue, 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 industry.
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.
High Frequency Wheel Probe
A new high frequency dry coupled wheel probe developed and patented by Sonatest. This new dry coupled solid contact wheel probe, overcomes problems with couplant contamination, application and removal, plus the impracticalities of immersion systems. The “tyre” or delay material is constructed from specific hydrophilic polymers which demonstrate acoustic properties that ideally lend themselves to the implementation of Ultrasonic NDT. Frequencies of 2 to over 10 MHz are possible offering higher sensitivity and resolution. Also capable of employing pulse echo mode this enables depth measurements and examination options where access is limited. The HF Wheel Probe can be used in situ, reducing inspection time and eliminating the need for immersion tanks.
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.
Thickness Meter Probes (TMPs)

A range of transducers that were made for use with older style thickness meters. These are still suitable for use with modern wideband amplifier thickness meters. TMPs may also be used with flaw detectors where thin sections are to be tested.
Soft Tip Probes (STPs)
| Code | Contact
Diameter | Frequency | Dimensions | Spare
Tips | | STP5-1 | 5 | 1.25 | 9.8 x 30 | RST/5 | | STP5-2 | 5 | 0.5 | 9.8 x 30 | RST/5 | | STP10-1 | 10 | 1.25 | 20 x 36 | RST/10 | | STP10-2 | 10 | 0.5 | 20 x 36 | RST/10 | | STP15-1 | 15 | 1.25 | 25 x 36 | RST/15 | | STP20-1 | 20 | 1.25 | 30 x 36 | RST/20 | | STP25-1 | 25 | 1.25 | 35 x 36 | RST/25 |

Soft tipped transducers, as well as roller probes, are for use with Sonatest dry contact flaw detectors, UFDS 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
| Code | Frequency | Roller
Diameter | Dimensions | Spare
Tyres | | RP25HS-1 | 1.25 | 25 | 36 x 113 | PT25 | | RP25HS-2 | 0. 5 | 25 | 36 x 113 | PT25 |
|  |
Dry contact roller probes are used where automated testing is required. Roller probes have miniature BNC connectors.
If there is not a transducer available here for your application, we can build one that will be!
