ELECTRICAL FIELD SENSORS

摘要

The present disclosure provides several systems. In general, it provides E-field sensor systems that utilize at least one electrode (100) adapted for creating an E-field in an area (210) within a detection volume where fluid presence (400) or presence of a solid body (300) is to be detected. The electrical field sensor is configured to generate a detected signal responsive to a change in capacitance of the electric field, and is communicatively coupled to the electrode (100). In addition, a processor (275) is configured to determine a quantitative measure of a fluid or solid body within the detection volume in accordance with a capacitive relationship with the detection volume. Described are examples of the system for fluid presence detection, fluid level measurement and measurement of proximity to a solid object.
