FORCE TRANSDUCER Russian patent published in 2008 - IPC B61K9/08 E01B35/12 G01G19/04 

FIELD: transportation.

SUBSTANCE: invention relates to methods and devices intended to measure the rolling stock weight in operating conditions without stopping the said rolling stock and in inclined track automatic control systems. The force transducer incorporates a signal processing unit and a sensitive element fitted on the rail and made up of a passive and active parts moving relative to each other, the passive part being fitted directly on the rail while the active one being fitted on a rigid beam mounted on two hinged supports equidistant, along the rail, from the passive part. The aforesaid passive part represents a bush with an inner and outer threads and is fastened, by means of outer thread and nut, in the rail web hole, while the bush inner thread serves to locate a threaded stepwise rod made from a nonmagnetic material accommodating a magnetic material insert on its end face closer to the sensitive element active part. The said insert magnetisation vector is parallel to the measuring rail direction. The sensitive element active part incorporates a magnetic field intensity meter.

EFFECT: higher measurement accuracy.
