Abstract

PURPOSE:To obtain a temperature detector which requies no cell and no connection and facilitates maintenance by a method wherein a resonance frequency of a resonant circuit consisting of components having large temperature coefficients is detected through the intermediary of a coil connected electromagnetically to this circuit. CONSTITUTION:A temperature detector 1 froms a rsonant circuit consisting of a capacitor 2, a reactance 3, etc. having large temperature coefficients, and performs oscillation with a resonance frequency fo or the like corresponding to a temperature to. Accordingly, when an oscillation frequency from an oscillating circuit 6 is changed through the intermediary of a detecting coil 5 connected electromagnetically to the detector 1, the resonance frequency fo is detected by a detecting circuit 7 and thereby the temperature to is determined. By this constitution, a temperature detector requiring no cell, connection, etc. and facilitaing maintenance is realized.
