LINEAR ACCELERATION PICK-UP Russian patent published in 2005 - IPC

FIELD: measurement technology.

SUBSTANCE: linear acceleration pick-up can be used in systems for diagnosing condition of industrial robots. Pick-up has magnet system made of two permanent magnets fixed by plugs. There is thread onto inner surface of plugs. System is placed inside case; space between magnets if filled with viscous fluid. Additional third magnet is installed between first two ones for free movement. The third magnet is oriented to the rest two ones with like poles. Edge surfaces of the third magnet and surfaces of other magnets turned to those surfaces are covered with conducting layer, for example, with metal. Surfaces of the third magnet are connected together and brought into measuring circuit. Design of the pick-up allows adjusting of sensitivity due to screwing-in and- out of plugs.

EFFECT: simplified design; improved reliability of operation.
