U31 Probes

Specifications

The table below provides specification details for regular probe types. The range is not limited to those listed.

TSC can manufacture to-order many of the probe types listed below with additional options:

  •  Std cable length is 5m unless otherwise specified. Other lengths 1m - 50m available.
  •  For deployment in shallow water, probes can be provided for use down to 50m depth.
  •  For use with non-magnetic materials, high frequency versions can be supplied.
Underwater Weld Probe Documentation

[Picture: Type 293]

"The most stable probe to deploy, using three point contact. Produces the most uniform field over the largest area and should be used whenever access allows"

Bottom face is fitted with stainless steel feet and replaceable if worn. Sensors are protected by a high wear resistance ceramic disc and replaceable brass location plate.

"This probe gives good access into tight spaces, under rat holes etc."

These allow inspection of tight-access areas, allowing difficult geometries to be inspected from various approach angles.

Sensors are protected by a high wear resistance ceramic probe nose.

336 Straight 5 kHz
No
For underwater use. General tight access
337 Right Angle 5 kHz
No
For underwater use. Good for side approach circumferential access.
352 Right Angle Transverse 5 kHz
No
Good for end approach circumferential access
 
Underwater Micro Pencil Probes Documentation

"Similar to Mini Probes but with smaller sensor coils. Gives greater sensitivity to small cracks"

These probes allow tight-access inspection and are specifically designed to locate shallow/small defects.

Sensors are protected by a high wear resistance ceramic probe nose.

353 Straight 5 kHz
No
Tight access.
354 Right Angle 5 kHz
No
Good for side approach circumferential access.
355 Right Angle Transverse 5 kHz
No
Good for end approach circumferential access.
 
Underwater Ground Weld Probe Documentation

"This probe gives good access into ground areas and tight geometries"

These probes allow the bottom of toe burr ground areas to be inspected. They are also useful for various tight geometries and corners.

Sensors are protected by a high wear resistance stainless steel covered probe nose.

Universal Shallow Water Array Documentation

[Picture: Type 311]

"This array performs fast wide area inspection with software that allows differentiation between defects and features"

This probe is designed to span large areas, typically inspecting across a region or a geometric profile. Software allows visualisation of plan views of an inspection area using colour contour plots to gauge defect density and location.

This array probes features full position feedback using a rotary encoder with sprung wheel, providing precise defect location and sizing detail.

Array probes can be manufactured to suit requirements, providing a 'fit' for a distinct geometry or inspection path, for example propulsor blades, ships propellers, shafts etc.

Typically 8 rows of sensors and a Y Field capability provide an excellent analysis of potentially defective areas.

311 Universal Shallow Water Array 5 kHz
Yes
General flat underwater inspection to 50m depth.
 
Underwater Static Array Documentation

[Picture: Type 130]

"The probe is simply placed in a series of overlapping positions around the weld enabling deployment by workclass ROV's"

Welds can be inspected in a series of pick and place operations, avoiding the need for sophisticated weld tracking. The system can be deployed by virtually any workclass ROV fitted with a good quality manipulator.

130 Static Array 5 kHz
No
