DETECTING THE CLOGGING OF A FLUID FILTER

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, an...

Zusammenfassung:	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 then sending a clogging signal SC representative of the filter being clogged when the first derivative {ΔP}′ is equal to zero.
