Abstract

The Thermomarker is the first industrial application of copper based shape memory alloys which knows a very large spreading. It's a tester that gives a signal very easy to read. However it is a precision instrument and its testing remains an essential care.

The paper will explain the special feature of the Thermomarker which falls in with two tests of working: one during the martensite → austenite transformation, one during the austenite → martensite transformation. We shall expose what kind of working test (in fact a screening inspection) we have set up to get a good accuracy and a whole reliability even on a mass production.

Then we shall expose our system of production tracing that is able to trace back the whole historical account of any Thermomarker.
