摘要： The invention concerns an electrical impedance detector for measurement of physical quantities, in particular of temperature or humidity, as well as a process for manufacture of the detectors. The impedance detector is composed of pieces cut off from a continuous detector filament (20). The detector filament (20) comprises an electrically conductive pair of electrode wires (10a,10b) or an equivalent assembly of electrode wires, on/between which there is an active material (11) whose impedance properties are a function of the physical quantity to be measured. The different electrode wires (10a,10b) of the detector filament (20) in the pieces of detector filament (20) have been cut off at different points (41a,41b), compared with one another, so that the impedance (CM) to be measured will be formed in the area (CV) between the cut-off points (41a,41b) of the electrode wires (10a,10b). As the starting material of the active material layer (11') in the detector, a glass paste (11P) is used, through which the pair of electrode wires (10a,10b) is drawn through the drying oven (34) onto the receiving frame (35). The stage of crystallization of the active material layer takes place in a separate heat-treatment stage which takes place after the winding stage.
