Detection of the clogging of a fluid filter
The method involves measuring pressure difference between an upstream and a downstream of a fluid filter (20) by a sensor (160) at successive sampling instants. Derivative of the pressure difference with respect to time is calculated at different instants by a logic controller (165). A filter cloggi...

| description | The method involves measuring pressure difference between an upstream and a downstream of a fluid filter (20) by a sensor (160) at successive sampling instants. Derivative of the pressure difference with respect to time is calculated at different instants by a logic controller (165). A filter clogging signal is sent when the derivative is equal to zero. A threshold signal is sent when the pressure difference exceeds a threshold value, before sending the clogging signal. An independent claim is also included for a device for detecting clogging of a fluid filter, mounted on a fluid system. |
