Temperature sensor element in temperature-measuring device

摘要

There ist provided a temperature sensor element in a temperature-measuring device using a thermocouple (3) having excellent insulation property and having a simple assembly procedure. The temperature sensor element comprises a temperatur-measuring means (2, 2a, 3) consisting of a heat-resistant protective tube (2, 2a) having a thermocouple (3) inserted therethrough, compensating conduction means (8a, 8b) having connecting sections (7a, 7b) which connect a pair of extension sections (6a, 6b) of a thermocouple element (3) extending from the protective tube (2) respectively, and support means (9) to join and hold mutually the temperature-measuring means and the compensating conduction means (8a, 8b). The end of the protective tube (2) and the compensating conduction means (8a, 8b) are held under the condition that they face the support means (9) and that the extension sections (6a, 6b) of the thermocouple element and the connecting sections (7a, 7b) of the compensating conduction means (8a, 8b) are inserted into holding chamber means (14a, 14b) provided in the support means (9). Then the holding chamber means (14a, 14b) is filled with a filler (2) which is hardened to bury and fix the end (5, 5a, 5b) of the protective tube, the extension sections (6a, 6b) of the thermocouple, and the connecting sections (7a, 7b) of the compensating conduction means (6a, 6b) in the filler (2).
