Abstract
Electronic device for monitoring the temperature of a medium ensures that the temperature has not reached pre-established index limit values. The device includes contacts for closing an electric charge flow circuit when the temperature reaches an index limit value, an electric charge storage component connected to the charge flow circuit when the contacts close, the charges remain stored as long as the temperature does not reach one of its index limit values, and is able to flow through the charge flow circuit when the circuit is closed by the contacts, the charge storage not returning to the charge state which they had before the charge flow circuit closed if the latter opens again, and a provision for reading enabling the charge state to be determined.
