Abstract
A method of detecting clogging of a fluid filter is disclosed. The method includes measuring, at successive sampling instants, the pressure difference ΔP from upstream to downstream across the filter, calculating the first time derivative {ΔP}' of the pressure difference ΔP at different instants, and sending a clogging signal Srepresentative of the filter being clogged when the first derivative {ΔP}′ is equal to zero.
