Electrical impedance detector for measurement of physical quantities, in particular of temperature
First Claim
1. Electrical impedance detector for measurement of physical quantities, in particular of temperature, which detector comprises electrodes (11, 14), between which the electrical impedance (C;
- R) that represents the physical quantity to be measured is measured, and between which electrodes (11,
14) there is an active material whose impedance properties are a function of the physical quantity to be measured, characterized in that the active material of the detector is a very thin thread-like glass-ceramic fibre (10) which has been manufactured by means of the glass-drawing technique.

Abstract
Electrical impedance detector for measurement of physical quantities, in particular of temperature. The detector comprises electrodes (11,14), between which the electrical impedance (C;R) that represents the physical quantity to be measured is measured. Between these electrodes (11,14) there is an active material whose impedance properties are a function of the physical quantity to be measured. The active material of the detector is a very thin thread-like glass or glass-ceramic fibre (10), which has been manufactured by means of the glass-drawing technique. Further, a process for the manufacture of said detectors is described.
