6. Associated instrumentation
Downstream, the sensor is followed by electronic instruments whose role is to amplify the signal so that it can be used either to read a measurement, or for a control action, with all the possibilities offered by microprocessors. Obviously, it is essential that this instrumentation performs in a way that does not alter the characteristics of the preceding sensor.
the description of these amplifiers and other electronic devices does not concern the present article.
A measurement chain is an inseparable whole; in particular, the instrument input that follows the sensor can, by its very nature, alter the performance obtained using the procedures described above

Extensometry does not lend itself to the establishment of standards as such. However, the documentation booklet below recalls, among other things, the concepts of elasticity which form the basis of extensometry.

...French and foreign organizations
The applications of extensometry are so varied that the technique is occasionally discussed by numerous technical associations. However, a number of industrial countries have set up associations or groups specializing in experimental stress analysis, of which extensometry is a major branch.
