Eddy Current Testing Equipment

Product Details:

The FOERSTER MAGNATEST D 3.623 is an electronic instrument for non-destructive testing of conductive materials for their different magnetic and/or electrical properties.

It is ideal for testing mass-produced components (such as fasteners, shafts, studs, rings, valves, sprockets, gears, forged parts, cast parts, machined parts, sintered parts, and more) for differences in:

• Alloy Composition
• Heat treatment
• Grain Structure
• Hardness
• Case Depth
• Dimensional and Geometrical Differences

Features & Benefits:

• PC controlled electromagnetic test electronics for fully automated and rapid testing of every individual component produced (can also be employed manually and offline)

Automated micro-structure and hardness testing with coils and probes:
The sensors for testing material properties are available as coils or probes, depending on the material concerned. A broad range of standard testing coils and standard testing probes is available for the various MAGNATEST test instruments. In addition, we offer individually adapted customized solutions for special sizes or geometries.

Effective demagnetization via the pulse method

Magnetized components can lead to interference signals during crack or microstructure testing with eddy current component conditions, therefore resulting in false readings.

To avoid this, FOERSTER offer a powerful demagnetization unit: the ZMAG CM. The pulse method used enables high penetration depth to demagnetize the components effectively and promptly. The Siemens control and pre-configuration allows an easy integration of the unit into your production process. Thus, your process quality and reliability can be significantly increased.

Material evaluation based on magnetic properties

Magnetic values such as coercivity HCJ correlate with numerous important process parameters and material properties in the production of sintered hard metals and powder-metallurgical components. The KOERZIMAT 1.097 HCJ measuring system by FOERSTER facilitates the accurate, automatic, and fast measurement of the coercivity HCJ. The largely geometry-free measurement is particularly suitable for testing samples with complex shapes. The extension module J-H measurement offers the possibility to determine the complete J-H Hysteresis on soft magnetic steel incl. the initial curve.

The applications of the KOERZIMAT include the control of the sintering level and particle size of hard metals and the quality control of metallic powders for the production of magnets and hard metals.

Compact and robust, the STATOGRAPH CM+ / CM consists of powerful hardware and software to guarantee reliable inspections. Both STATOGRAPH modules are network-compatible and can thus be operated via a tablet or smartphone. Production line status can therefore be checked anytime and anywhere, meaning that immediate corrective action can be taken if necessary. Test parameters and other settings can be captured and adjusted on the fly.

The STATOGRAPH CM+ also has a touch screen for use directly in the line.

On the STATOGRAPH CM, a multi-color LED tells the device status with a quick glance into the control cabinet.

SENSOR TECHNOLOGY:
All existing probes can be connected as usual to the new STATOGRAPH CM+ / CM modules. A broad portfolio of standard and special-purpose probes is available. This means that, with FOERSTER, you’re optimally prepared for any challenge.
Standard probes:For crack testing on components, stationary differential-eddy-current probes are usually installed directly in the test station. These have a very high test sensitivity and generate reproducible test results.
Special probes:Components with complex geometries require special test solutions. For this reason, FOERSTER’s probe portfolio includes, among others, angled sensors and its FLEXPROBES, which are flexible probes that can be adapted to the unique geometry of the test piece.
In addition, we can also develop customer-specific  probes for high-resolution testing.

Multi-Channel Eddy Current Testing at the Highest Level

With the CIRCOGRAPH DA, FOERSTER sets new standards in non-destructive eddy current testing of long products such as tubes, bars and wires for longitudinally oriented surface defects. CIRCOGRAPH DA offers unsurpassed reproducibility at high test speeds by combining advanced digital electronics with sophisticated system architecture. Digitization takes place directly at the sensor. In order to reduce possible interferences from the outside, the signal paths of the analog test signals have been reduced to a minimum. Equipped with the latest technology and intelligent details, the CIRCOGRAPH DA can also be integrated into existing production lines.

Better Overview by Visualization of the Test Signals as C-Scan

The new product generation CIRCOGRAPH DA enables displaying of the test signals as a C-Scan. The signal sequence is shown as usual as the sum signal over the distance. The defect position is displayed in the longitudinal direction. Additionally, in the C-Scan view, the signals are now also displayed in the circumferential position. The operator is thus given a better overview of where and, above all, how the defect propagates on the material surface.

NON-DESTRUCTIVE CRACK TESTING WITH ROTATING PROBE

The CIRCOFLUX test system is used for the non-destructive surface testing of ferromagnetic steel bars using the magnetic flux leakage method in accordance with standard EN 10221. This method is the most sensitive surface testing method for longitudinal, crack-like defects in hot-rolled ferromagnetic steel bars. The CIRCOFLUX sensor system therefore replaces subjective testing methods such as the magnetic powder test (magnetic crack detection) and visual checks, which are difficult to document and reproduce.

The available sensor systems cover a material diameter range from approx. 10 to 180 mm. FOERSTER''s long-standing experience in this field ensures high operating reliability. The modular design of the test electronics is also ideally suited to meet future demand for ever increasing defect detection sensitivity.

Your advantages at a glance

• Easy operation using modern touchscreen display
• Network integration in existing production and quality systems
• Integrated diagnostic and documentation function for compiling your test results
• Relational database for high data integrity and open port to other applications
• Maximum detection sensitivity of defects from 0.1 mm depth on ferromagnetic rods with hot-rolled surface
• Test material diameter from 10 - 180 mm
• Pivoting test levers also tolerate non-straight material and protect against damage to or destruction of the test elements
• Central adjustment to the test diameter minimizes the risk of adjustment errors
• Automatic dimensions adjustment reduces setting up time and increases productivity

New dimensions in component testing With STATOVISION, FOERSTER offers an innovative software solution for the identification and visualization of heretofore undetectable errors. Intelligent filter algorithms enable previously impossible inspection tasks; since this allows interference signals to be filtered out and suppressed, cracks near drill holes or millings, for example, can be found. Furthermore, by superimposing the images of several components, it is possible to identify at an early stage patterns in the defects, e.g. due to tool wear, so that the source of the error can be eliminated.
Advance Features:

• Intelligent filter algorithms for targeted suppression of interfering contours like drill holes, grooves, bevels, etc.
• High-resolution representation of the component surface
• Digital filters with large dynamic range
• Post-data analysis for process improvement, since raw data can be stored and post-processed
• Report creation in PDF, PNG and CSV formats
