Abstract

See full text

A method and an apparatus for measuring mass based on torque equilibrium, including a main blade for supporting and balancing a lever and parts arranged on the lever; a displacement measuring device for measuring a position of the lever; an electromagnetic torquer for balancing the apparatus after a balance weight is coarsely loaded during measuring; a product tooling on which a product to be measured is arranged and fixedly connected. The product tooling is fixed on a slider which freely slides along a guide rail; a locking block is provided to lock the product after the product slides in place; the guide rail is fixed on the level; a laser displacement sensor is provided to measure a displacement of the product along the guide rail; a lifting mechanism is provided to lift the lever and parts arranged on the lever to separate from the main blade.
