Inclination switch of float switch used for determining filling level of liquid e.g. acid in container, has radio frequency identification chip, power supplies and movement enhancement inclination switch elements which induce voltage

摘要

The inclination switch has radio frequency identification (RFID) chip (202), power supplies and movement enhancement inclination switch elements, in which switch elements are used for inducing voltage. The power supply is provided with a coil (203) and a permanent magnet (204). The switch element is provided with guide rod (201), ferrite core (205), notches (207,208) and plate spring (209). A weight of switch element is selected from ball, ring, cylinder made of iron, magnetic circuit with ferrite core or iron core, and coil with ferrite core or iron core.
