DEVICE AND METHOD FOR DETECTING A TEMPERATURE VARIATION, IN PARTICULAR FOR DETECTING A CRYOGENIC LIQUID LEAKAGE

摘要

The inventive device for detecting temperature variations comprises a hollow thermally conductive tube (1) for containing liquid (3), wherein said thermally conductive tube (1) consists of a first end (6,7) and a second end (7,6) one of which (6, 7) is connected to said sensor (4) and at least on of which (7,6) is sealed. Said device for detecting a temperature variations makes it possible to detect cryogenic, cold, hot and ultra-hot liquid leakage.
