Digital Display Portable Electromagnetic Principle Eddy Current
Conductivity Meter HEC-101
HEC-101 is a kind of eddy current electrical conductivity tester,
which is designed for quick & convenient measurement of material
property, such as material separate,quality control,material state
check and so on. It uses the electromagnetism testing principle.
Testing objects focus on non-ferromagnetic material.
Ⅰ,Principle
Eddy current exam is an NDT method established on the basis of
electromagnetic induction principle; it is suitable for the
conductive materials. Put the conductor in the alternating magnetic
field, if inductive current exists, namely eddy current. On account
of the change of each conductor’s own factors (for example:
conductivity, magnetic conductivity, shape, size and flaw, etc),
will cause the change of the current, so we can use this phenomenon
to judge the conductor’s character or state and whether flaw
exists.
Eddy current test is to put the conductor close to the alternating
current coil, the coil establishes alternating magnetic field, this
alternating magnetic field transits the conductor, and has the
electromagnetic induction with it, establishes eddy current in the
conductor. The current in the conductor also can produce its own
magnetic field and can change the alternating magnetic field to be
strong or weak, then causes the change of the voltage and R
resistance. Therefore if the conductor’s surface or the near
surface has flaw or the metal material changes, the intensity and
the distribution of the eddy current will also change, so as the
change of the voltage and R resistance, according to this change,
the eddy current may indirectly know about the flaw in the
conductor and whether the performance of the metal material changed
Ⅱ,Features
★The meter uses 60 KHz (aviation industry standard) to inspirit.
★The testing data can be read in two kinds of unit: %IACS and MS/m.
★Its big typeface, the back light illumination designs are
advantageous for users to take the testing data even in low light
condition.
★It uses the high property battery to make sure it keeps more
running time, and because of its mini-size, it is easy to carry and
to grasp hold.
★The design of the meter is more advantages: user can replace the
probe in the outdoor, don’t need to return to the company to adjust
the probe into matching the meter.
★It can hold measurement data.
