Automated calibration of length change sensors (extensometers).
Quality assurance per DIN ISO 9000 requires that measuring instruments
must be checked at specific intervals depending on the frequency
and type of test equipment used.
A length change sensor is such a measuring instrument. Length change
sensors, also known as extensometers or strain sensors, are implemented
in a wide variety of areas related to material testing, as well
as in research and development. This involves measuring changes
to the material structure or yielding of materials up to the nanometer
