Title: Temperature sensor
Inventor: WAKAHARA KOUJI
IPC: G01K7/36
Filed: 1980-10-22
Abstract: PURPOSE:To manufacture a titled temperature sensor to be used for detecting an abnormal temperature which has a simple structure and which stably functions for a long period, by installing plural temperature sensitive switches which work at temperature higher than or lower than a prescribed temperature between two condutors. CONSTITUTION:Plural temperature sensitive switches are connected in parallel between two conductors, so that they work at temperatures which are higher or lower than a prescribed tempeature. For example, a permanent magnet 18 and a magnetic material 19, both of which are electrically nonconductive, are connected in parallel by yoke materials 20 and 21, and contactors 22a and 22b made of a magnetic substrnce are fitted to the termnal of the yoke materials as shown in the diagram. While the magnetic path passes through the magnetic substance side and the contactors are kept under the opened condition at temperatures which are lower than the curie point of the magnetic substance, the magnetic path passes through the contact piece and the contactors are kept under the closed condition at temperatures which are higher than the curie point. Therefore, when a plurality of this type temperature sensitive switches 14 are fitted in parallel between conductos 13a and 13b, and the distance up to short-circuiting locations is measured by an ohmmeter 31, locations where abnormal temperatures are generated can be detected.
