Abstract

The proximity detector includes a probe (4) and a printed circuit (3), contained within a case (33) which is closed by a lower cap. A plug (35) with connection pins (36) running through it, closes off the other end of the case. Said plug (35) also includes a filling funnel (13) allowing through a resin which can be hardened and which is able to enter once the container has undergone centrifugation. Said resin forces the air out through interstices (i3) which the resin itself cannot penetrate. During this operation, the funnel is held sealed between elastomer parts belonging to two centrifuging rotor elements which define a recess for the apparatus. Application: faster and more efficient filling.
