Abstract

A method for in-line control of the integrity of a filtering system implemented during an industrial process including the filtering of a gas through the filtering system, the filtering system including at least one filtering cartridge, the method including at least the following steps: —a measurement step (S) which involves measuring a pressure difference ΔP representative of the pressure loss caused by the filtering system (F; F), —a testing step (S, S) which involves comparing the measurement (S) with a predefined high threshold (Sh) and a predefined low threshold (Sb), in such a way as to consider the at least one filtering cartridge to be non-compliant when the pressure difference measured in the measurement step (S) falls outside a range located between the high threshold (Sh) and the low threshold (Sb).
