Electrical Eddy Current Testing Equipment Digital Portable 60KHz
Introduction
HEC-102 is a kind of eddy current electrical conductivity meter, 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, and the testing data can be read in two kinds of unit: %IACS or MS/m.
★Its big typeface, the back light illumination designs are advantageous for users to take the testing data even in low light condition.
★Two kinds of operate languages satisfy different national demand.
★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 store 1000 measurement data.
