The CMS flat concentrator is designed for copying relief surfaces with unevenness not
exceeding 0,5 mm at the base width of 11 mm The CMS flat concentrator has the strongest
magnetic flow compared to the other scanners. Thus, it is mainly used for examining structural
inhomogeneity of metal surfaces.
Rotary concentrators of the CMS are designed as the system of floating disks for
magnetic copying of more complex relief surfaces with unevenness not exceeding 1 mm at
the base width of 20 mm. The CMS rotary concentrators form surface magnetic flow. Therefore
they are mainly used for examination of relief inhomogeneity of metal surfaces (front side
of the number platform, defective welded seams). They have the highest penetrating ability
through lacquer-and-paint coating. Stronger magnetization is provided by the concentrator
with a smaller effective width. That is why the use of 15 mm concentrator is more preferable
for detailed examination. The use of 21 mm concentrator is more preferable for increasing
the examined area.
The compact magnetic scanner is equipped with a flat concentrator on permanent
magnets with effective width of 11 mm. Due to the minimal size the scanner can be used
on difficult surfaces: grooves, joints or abutment of examined object elements. Magnetizing
properties of this scanner occupy an intermediate position among the CMS concentrators.
The compact magnetic scanner is equipped with a spring clip which can be fixed in one of two
positions. The operator can choose a suitable position relative to the direction of scanning.
The most effective device for advanced examination of metal structure of objects is
the eddy-current scanner (supplied optionally). Its specifications are given in the user’s
guide to eddy-current magnetographing device Regula 7517B.
Magnetic tape cartridges are used for storing operating reserve of MT. The cartridges are
marked: 1) the cartridge for MT that has recorded information is marked with a red marker,
2) the cartridge for demagnetized MT is marked with a green marker. Cartridges can be either
attached to magnetic clamps (Figure 6) or kept separately.
Magnetic clamps are used to fix a MT strip on the examined area during magnetic copying.
Use a container with operating reserve of alcohol and a brush when preparing the object
surface for magnetic copying. Use a marker for marking magnetic copies.
