A leak detection device includes a space intended to receive a part to be tested, at least two electrodes disposed on either side of the reception space, a direct-current electrical power supply supplying at least one of the electrodes with an output voltage, and a current detector configured to measure the current generated by the voltage difference between the electrodes. The electrical power supply is a power supply including a transformer having a midpoint primary, a transistor connected to said midpoint of the transformer, switches whose succession of openings and closures has at least one duty cycle and enables the transmission of energy through the transformer, and at least one regulation circuit regulating the value of the duty cycle and the voltage supplying the base of the transistor.

Leak detection device and associated electrical power supply

The invention relates to a tracer gas leak detection system including at least one sensor delivering a signal, referred to as the sensor signal, which is representative of a concentration of the tracer gas at the sensor. The tracer gas leak detection system includes, for at least one given sensor, a corresponding phase advance correction device delivering a corrected signal from the sensor signal delivered by the given sensor.
