Zusammenfassung:The leak detector has a mass spectrometer (2) with a pumping unit (1), which produces a signal (q) proportional to the partial pressure of the gas present for which the spectrometer is adjusted. The pumping unit enables the equipment to function in sniffing or vacuum modes. The signal is passed through a differentiator (5), an amplifier (6) of ratio (A) and a low pass filter (7) which eliminates high frequencies not characteristic of a leak. The signal (dq/dt) produced is added (4) to the original signal in a summer (4) and used to produce a signal (qt) which denotes the leak.
