Abstract
The invention relates to a composite material, which comprises a sheet of insulating matter comprising on one face a meandering strip of Constantan covered with zones of copper, so as to define a fluxmeter formed by successive rows of individual thermocouples. Between the rows defined between the meanders of the strip are provided free spaces in which are made first patterns likewise of Constantan constituting a first arm of a thermocouple; the other face of the insulating sheet is coated with a sheet of copper in which are provided second patterns likewise of copper constituting a second arm of thermocouples. The first patterns and the second patterns are in electrical contact by metal welds also of copper, thus forming temperature detector thermocouples. A composite material is thus obtained forming a fluxmeter and a temperature sensor combined in a single device making it possible to detect the measurements in one plane, which is easy to manufacture.
