TENSION, REFERENCE, WORKING, HYDRAULIC MACHINE Russian patent published in 2011 - IPC G01L1/02 

FIELD: physics.

SUBSTANCE: proposed machine consists of structural frame with reference and tested force transducer loading zone, power hydraulic cylinder, pump unit with load controller, reference electric force transducers (1^st category standards) with force indication unit, control unit, mounts for force transducers to be tested, hydraulic and electric lines to interconnect machine assembly units and parts. Besides, machine incorporates reversing frame to mount reference standards and compression and expansion dynamometres to be tested, and extra hydraulic cylinder with force reference standard (1^st category standard) rated at limit load lower than that of proposed machine.

EFFECT: possibility to check up both compression and expansion dynamometres.
