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-ScanThe 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- Standardized hardware and software for all FOERSTER test instruments simplifies the handling
- 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
