The
Rail Probe
- Specifically
designed to contain two angle probes (2MHz, 70°) at either end
and a compression probe in the middle (2MHz).
- The
Rail Probe was used in combination with a flaw detector and railcart
to scan rails and has proved to be a very successful transducer,
manufactured exclusively by Sonatest Plc.

HF
Wheel Probe
- A
new high frequency dry coupled wheel probe developed and patented
by Sonatest Plc.
- The
main driving advantage of this dry coupled solid contact wheel
probe is that it works to overcome problems with couplant contamination
(application & removal) as well as eliminating the practicalities
of immersion systems.
- The
"tyre" or delay material is constructed of hydrophilic polymers
which have acoustic properties that lend themselves ideally to
the implementation of ultrasonics.
- Applications
include thickness measurement, composite inspection, delamination
detection and general flaw detection.

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.
- 5
MHz with an increased toe in angle to produce a short focal length
to suit such weld and are available as 70° & 60°, with BNC
or LEMO1 to fit flaw detectors.

Asia
Single Angle Range (ASA)
- A
high specification transducer with high signal to noise ration
and a very small dead zone.
- Employs
a lead zirconate 10 x 10 crystal, with the standard Japanese reference
number engraved on the brass/nickel plated casing.
- Also
has engraved scale.
- Index
point is 10mm from the front edge with an angle tolerance of >69°<70°.
- Also
available at 45° and 60°.

Thickness
Meter Probes (TMPs)
- A
range of transducers originally made for use with the older style
thickness meters.
- Suitable
for use with modern wideband amplifier thickness meters.
- Also
good for use with flaw detectors where thin sections are to be
tested.
|
 |
Soft
Tip Probes (STPs)
- Soft
tipped transducers are for use with Sonatest dry contact flaw
detectors UFDS and MS310D.
- Applications
include the testing of composites, rubber, wood, ceramics and
friction material.
- No
surface preparation required for the majority of applications.
- Ideally
suited for test specimens with complex shapes

 |
Roller
Probes
- Dry
contact roller probes are designed to be used where automated
testing is required.
- Roller
probes have miniature BNC connectors.
- Can
be used in combination with dry contact flaw detectors, UFDS and
the MS310D.
|
 |
Time
of Flight Diffraction (TOFD) Probes.
- All
TOFD transducers are highly damped with short pulse length,
broad bandwidth and high sensitivity, utilizing lead metaniobate
crystals.
- One
major application of TOFD is the ultrasonic examination of welds
after final heat treatment and/or hydraulic testing, to verify
the absence of cracks not detectable by radiography etc.
- Also
used to monitor welds during the service life of components.
