摘要: The switch has a measuring circuit (5) positioned such that an electromagnetic signal fed into the undergoes change. A reference (6) is remains unaffected by level of medium. measuring-voltage tap (8) and voltage (9) at specific points on circuits determine voltage, respectively. comparator (12) compares with emits comparison-derived signal. An independent claim also included for method detecting fill medium in container.
