Measuring device, measuring arrangement and method for determining a measuring signal while moving an indenter into a specimen surface

摘要

The present invention detects the measurement signal during the intrusion movement of the intruder (41) on the surface of the test body (14), especially for hardness measurement, or detects the scratch resistance of the surface of the test body (14). A measurement system, a measurement configuration and a method for detecting a measurement signal during a scanning movement of an intruder (41) on the surface of a test body (14), in order to determine the surface roughness or in particular to determine the surface roughness, The measuring system has a housing (47) with force generating means (44), and also at least one first measuring device (78), the force generating means (44) operating with the intruder (41). Connectable to generate a displacement movement of the intruder (41) along the advancing axis (48) of the intruder (41), and to control the intrusion movement of the intruder (41) on the test surface of the test body (14). Activate or place the intruder (41) on the surface of the specimen (14) and scan At least one first measuring device (78) measures the penetration depth into the surface of the specimen (14) or scans the penetrator (41) over the surface of the specimen (14). Meanwhile, the displacement movement of the intruder (41) along the displacement axis (48) of the intruder (41) is measured, and the force generating device (44) activates the displacement movement of the intruder (41) by magnetic force.
