Abstract
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.
Claims12
A tracer gas leak detection system comprising at least one sensor operable to deliver a sensor signal (Ve) representative of a concentration of a tracer gas at said at least one sensor, characterised in that, for each of the at least one sensor, said system further comprises a corresponding phase advance correction device operable to deliver a corrected signal (Vs) from the sensor signal delivered by each sensor, said correction device comprising:
- at least one overdamped correction cell configured to approximate a correction of the proportional-derivative type;
- and
- at least one underdamped correction cell configured to approximate a correction of the proportional-derivative type.
