APPARATUS FOR THE DETERMINATION OF THE QUANTITY OF PARTICLES IN A CONTAINER |
摘要 |
Apparatus is disclosed for determining the quantity of particles present in a container. A sensor device is movably mounted in the container and is in contact with the particles. When the filling height in the container falls below a predetermined value, an electrical switch is actuated and emits a signal to an indicator. The sensor device comprises a flap fixed on an axle rotatably mounted in the container. A resilient element presses the flap against the quantity of particles and a cam is mounted on the axle. On rotation of the axle, the cam actuates the electrical switch. |
