Abstract
The invention relates to a method for monitoring a leak detector comprising: a secondary vacuum pump designed to be connected to a primary vacuum pump, the secondary vacuum pump comprising a motor, a rotor and a stator, the said rotor being capable of being rotated in the stator by the motor when the motor is powered, and at least one information means capable of being powered electrically, in order to inform a user of the operating state of the leak detector,
- characterized in that, in the event of the motor power supply being cut off, the kinetic energy of rotation of the secondary vacuum pump rotor in the form of electrical power (101) is recovered in order to power the information means (102). The invention also relates to a leak detector (1) using the said monitoring method.
