DEVICE FOR CHECKING OF STRAIN-GAUGE BALANCE Russian patent published in 2009 - IPC G01G23/01 

FIELD: physics; measuring.

SUBSTANCE: invention concerns to field of weight measuring technics and is guided on increase of productivity of checking and expansion thus functionality. This effect is provided because the device for checking of strain-gauge balance contains the hydrocylinder with a rod and the hydraulic pump mounted on the basis, the analogue-digital transformer and a numeral diagramme board. According to the invention, it is supplied by the asynchronous electromotor which arbour is interfaced to the pump, a frequency transformer which exit is electrically related to the drive, the reference strain-gauge indicator which exit is joined to an inlet of the analogue-digital transformer, and the reference strain-gauge indicator is erected on a hydrocylinder rod in such a manner that pressure from a rod is transmitted on reference strain indicator and the strain-gauge indicator of calibrated scales, besides, the device is supplied with the microprocessor, the block of the target signals which exit is joined to an inlet of a frequency transformer and an inlet with a microprocessor output, communication interface RS and the keyboard.

EFFECT: increase of productivity of checking and expansion of functionality.
