Standard Smart Probes

The probe supplies a measurement signal relative to the coating thickness. Proper probe selection and the quality of the probe determine the accuracy of the measurement for any particular application.

Within the FISCHER System, every smart probe works with every instrument (provided that the measurement method of probe and instrument are the same). This unlimited ability to combine allows the operator to cover diverse measurement applications simply by changing probes.

The many different applications require probes of different design and shape. The FISCHER System family of smart probes includes many different designs. A general distinction can be made between standard probes and custom probes. FISCHER develops custom probes for specific measurement applications that are not covered satisfactorily by standard probes. The company's application engineers are constantly working on new solutions.

When using a standard probe, model selection is determined by a number of criteria. The first criterion is the coating/substrate material combination. This determines the measuring method of the probe - Eddy current or magnetic induction. The use of dual measurement probes are increasing in popularity They operate according to both measurement methods and can be connected to the DUALSCOPEŽ MP20E-S. The EDX10 probe is designed for the measurement of dual layers (paint or laquer/zinc-layer on iron). This Product grouping features a selection of available probes.

Geometric conditions of the measurement area determine the shape of the probe. Radial, axial, and right angle probes are available. The ETD3.3 Eddy current probe is ideal for curved surfaces. This unique probe gives correct thickness readings even on curved surfaces.

In the end, the probe that promises the optimal result is determined by a number of other aspects. Very important are the thicknesses of the coating to be measured and of the substrate. Coating hardness and surface roughness needs to be taken into consideration; often, two-pole probes exhibit better results on particularly rough surfaces. Other considerations are the curvature and size of the measurement area.
