Fluid container sensor |
摘要 |
A fluid sensor apparatus for monitoring fluid in a container. The fluid sensor apparatus comprises a housing having an upper hook extending from a top thereof to allow the housing to be suspended. A lower hook is telescopically received in the housing and extends from a bottom thereof. The lower hook is adapted for suspending a fluid container therefrom. The lower hook is movable relative to the housing. A cam member is located inside the housing and is movable relative thereto. The cam member is coupled to an upper end of the lower hook. The cam member has a stepped gradation. A biasing member is coupled between a lower shoulder of the cam member and the housing. The biasing member is adapted to apply a force against the cam member to cause the cam member to be biased upward relative to the housing to an upper position. A switch is coupled to the housing and has an actuator located in relation to the stepped gradation of the cam member. The switch is in a first state when the cam member is in the upper position. The switch is in a second state when a load suspended from the lower hook overcomes the force of the biasing member causing the cam member to be moved to a lower position relative to the housing. An alarm coupled to the switch is operative to indicate a fluid condition when the switch is in one of the first and second states.
