<p>A filtration assembly comprises a container and sealed cover with an inner filter element (4) that is attached and sealed at one end to the cover and comprises a supporting structure (6) for a filtering material (5), two end caps (7, 8) and a coupling rod (9). The filter is fitted with a blockage indicator (17) with a connector (14) linked to the coupling rod, a stress gauge (19) and an electrical circuit. The connector is in the form of two strips (14a, 14b) that co-operate with connecting surfaces (16a, 16b) on the coupling rod, and the stress gauge terminals are linked to the two strips.</p> |
