PROXIMITY SENSOR FOR SENSING FLUID LEVEL IN A CONTAINER |
摘要 |
A sensor system for sensing liquid level in a bilge, for use in automatic bilge pump actuators. First and second field effect sensors are potted or sealed within a container or the bilge wall and are aligned in a vertical array and each comprise a substantially planar pattern of "electrodes" or conductive traces disposed on a printed circuit board (PCB) along with integrated circuits used to create a loop or arc-shaped electric field. As bilge liquid rises to the proximity or level of the field effect sensors, a change in the arc-shaped electric field is sensed and, in response, a bilge pump is automatically actuated to pump liquid out of the bilge. Optionally, the pump control can be programmed by use of a microprocessor to permit control of on-off timing and prevent undesirable effects of "sloshing." |
