FIELD: instrument testing equipment. SUBSTANCE: this apparatus can be used in testing operability and metrological accuracy of device used for measuring force on tool in pressure shaping operations depending on path covered. Apparatus has unit for converting and recording of measured parameter with receiving synchro and recording unit. Installed in apparatus body are transformer, main and additional electric motors connected to it. Main electric motor is kinematically connected with synchro transmitter of apparatus. Additional electric motor is connected through double-stage reducer to cam. Lever interacts with curvilinear surface of cam. Connected to lever is metal core of electromagnetic coil which functions as differential converter. EFFECT: higher efficiency. 3 dwg
