Probes : High-Precision Probes

• FISCHER probes are extremely robust and wear-resistant — they deliver precise measurements over a long period of time even on hard surfaces and after millions of uses.
• All probes are developed and manufactured in-house to strict quality standards.
• Each individual probe is factory calibrated at several reference points with the greatest care to ensure the highest possible degree of trueness.
• FISCHER’s patented conductivity compensation — used in all eddy current probes — makes it possible to adjust for different conductivities of the substrate material, e. g. different aluminum alloys, eliminating time-consuming on-site calibration on the actual substrate material while simultaneously achieving very high levels of trueness.
• Special probes for the eddy current method that automatically compensate for the influence of curvature on rounded specimens are available.
• FISCHER experts can develop (upon request) individual probe designs that offer maximal repeatability precision and trueness.

The heart of any electromagnetic measurement system is the probe; the quality of its signal ultimately determines the overall quality of the metrological solution. After years of continuous development and innovation, the FISCHER probe programme now encompasses some 100 probes designed to ensure optimal results for the widest variety of measurement applications.

The most important criterion for selecting the correct probe is the combination of coating and substrate materials. Further aspects to consider include the thicknesses of the coating and substrate materials, the size of the measurement area, and the shape and surface conditions of the specimen.
Of course FISCHER also offers comprehensive, expert advice to assist you in choosing the appropriate probe for any given measurement application.
