SigmaA/B/CComparison of Main Indicators of Series Eddy Current Conductors

1measuring range

A/B/B1/CtypeThe measurement range is wide, and in addition to commonly used copper and copper alloys, aluminum and aluminum alloys, it can also test low conductivity non-ferrous metals such as titanium and stainless steel. It is the only true full range instrument in China, which does not require separate purchase of high conductivity and low conductivity instruments. One instrument is equivalent to two other instruments for others.

IIWithdrawal compensation

Lift off compensation is an important indicator of eddy current conductivity meter, which refers to the ability of the instrument to overcome the thickness of non-conductive coatings (such as coatings, paints, etc.) on the tested object,A/A1/B/B1typeLike similar instruments abroad, it is also the only instrument in China with a lifting compensation of up to 0.5mm. Even if there are other impurities such as coatings or paints and uneven surfaces on the surface of the measured workpiece, as long as it does not exceed 0.5mm, it can ensure measurement accuracy.

IIIOperating Frequency

At present, the commonly used working frequencies are 60KHz and 500KHz. 60KHz is the standard for conductivity testing in the aviation industry, while 500KHz can only be used to measure the conductivity value of thin plate materials.BtypeIt is the only instrument in China that comes with high and low frequency dual probes, with a high-frequency probe frequency of up to 500KHz. The high-frequency probe can test ultra-thin workpieces ranging from 0.1mm to 0.3mm, so there is no need to worry about even the thinnest workpieces.

4Measure area

The diameter of the eddy current conductivity meter probe is generally between 13 and 14mm.BtypeEquipped with dual probes of different sizes, the diameter of the small probe can reach up to 8mm, and the probe adopts electromagnetic shielding technology. The measured object does not need to be larger than twice the size of the probe, and it can measure ultra small workpieces as small as 8mm, which can also be easily handled.

5Measuring surfaces and rapid sorting

BtypeThere is a unique curvature correction technology, a dedicated surface measurement mode, and a "∧" - shaped probe cover attached, which can also stably measure surface materials. andBtypeIt has continuous measurement function and can quickly sort materials by setting upper and lower limit alarms, achieving the highest work efficiency.

VItemperature compensation

Domestic instruments only have virtual temperature compensation mode, and accurate measurements can only be made when the calibration block is at the same temperature as the measured material.BType machineAdopting advanced German technology, it is the only instrument in China with true automatic temperature compensation, which can automatically compensate to the standard value even when the standard block and the measured material are at different temperatures.

7Store data

All models can store 500 sets of data and can be set to automatic storage without affecting operation speed. It is convenient to view test records at any time, eliminating the inconvenience of notes and reducing manual error rates. Except for the C1 type, it can be connected to a computer to transfer data for printing and organizing.

8measurement accuracy

Each modelThe indicator functions are different, but no compromise is made on the most critical measurement accuracy of the instrument. The accuracy of all models is as high as ± 0.5%~± 1%, which is the same as the highest standard of similar foreign instruments, ensuring the most accurate measurement results.

9Measurement parameters

Each modelThe instruments all have three measurement parameters, namely conductivity MS/m, conductivity% IACS, and resistivity Ω· mm ²/m. One click switching does not require manual conversion and is extremely convenient to use.
