METHOD AND APPARATUS FOR ELECTRICALLY INDICATING A GAS CHARACTERISTIC

摘要

An apparatus for generating a signal representing one of the density and the pressure of gas within a high voltage circuit breaker based on a dial position of a pressure switch includes a clip configured to mechanically couple to the dial, the clip including a magnet, and lens assembled into the switch between the switch housing and an outer component of the switch. The lens includes a sensor positioned within a cavity of the lens in alignment with the clip magnet to detect the position of the pressure switch dial from a magnetic orientation of the magnet, and circuitry for converting the detected position into an electric signal.
