probes hall effect and toroidal

hi everybody...
I have two question above probes hall effect and toroidal magetization..
The questions are:
1)I generally used the tangenzial probe to determinate the magnetic circular field and magnetic longitudinal field on piece during MT ispection... I had a new tesla meter with two probe and i have difficult on correct choose probe because during same ispection i have two different value on field if i use the normal probe or tangential probe. For megnetic circular (such as central conductor,direct current,ecc) i choose the tangential probe and for magnetic longitudinal (such as coil, induced current method,ecc) i choose the normal probe.. Is correct my choose on the use probe?
The second question:
2) Is necessary to have the AC current in toroidal magnetization or i can also use CC current?
I know that questions are difficul but i hope in your help..
Best regard

Extended Range Variable Wall® Piping Calibration Blocks for Longseam Inspection

This set of two blocks has been specially designed for situations where ultrasonic examination tak
es place circumferentially or “around the curve” for applications such as inspection of longseam welds in piping and vessels. Jointly designed by PH Tool and Holloway NDT, the blocks feature side-drilled hole reflectors positioned within novel compound-curves, each with multiple thickness steps. The unique design results in a light and compact form factor, with the largest block weighing just over 15 lbs and spanning just 16 ¾”. Coverage is provided for nominal pipe sizes from 6” to 10” in the small block and 12” to a whopping 56” in the large block. The compound OD curves and multiple wall thicknesses actually exceed ASME requirements, providing exceptional signal response and measurement accuracy. Properly managing beam divergence off the ID and stabilizing beam skew due to probe rocking is essential to maintaining a consistent calibration when inspecting lengthwise on curved surfaces.

NDT.net launches mobile-friendly design

NDT.net has revamped its website providing a mobile-friendly design.The front page received a comp
letely new design and all other sections are now reacting responsively on mobile devices. This has been a major step to make our website more user- friendly.

Conformable wedge transducer

The conformability is obtained with a flexible membrane filled with water between the transducer and
the inspected component. The coupling between the membrane and the component requires a small quantity of water or couplant. The conformable wedge combines the acoustic performance of immersion technique with good coupling and low attenuation.

PAUT Probes

Typical Phased Array probes have frequencies between 1MHz and 20MHz and the number of wafers is 10
to 128. M2 Electronics offers customers conventionally ultrasound probes and the ability to provide high-precision Phased Array Ultrasound Probes of up to 256 wafers. We can also customize the probe for our customers to meet the specific application requirements of the user.
