FLUID HEATING DEVICE

摘要

An object of this invention is to detect breakage of a conductor tube 1 before it happens and to prevent leakage of the heated fluid. More concretely, this invention is a fluid heating device 100 that applies heat to a fluid that flows in the conductor tube 1 of a helical shape by applying induction heat to the conductor tube 1 and that comprises an electrical connecting member 2 that constitutes a short circuit by electrically connecting each of required portions of the conductor tube 1, and a potential measuring instrument 4 that measures a potential of the conductor tube 1.
