REFERENCE WEIGHTLESS CALIBRATION MACHINE Russian patent published in 2013 - IPC G01L1/02 

FIELD: measurement equipment.

SUBSTANCE: reference weightless calibration machine consists of a loading module including a power frame formed with a base with power hydraulic cylinders with pistons-columns and a traverse, a reverse frame coaxial to the power frame and equipped with a device of its adjustment travel relative to the power frame traverse, resting on the power frame traverse through a reference compression force sensor and connected with the calibrated tension force sensor to the base, a system of loading hydraulic actuator of the control system, an indication system of loading force of a stationary reference force sensor, electric and hydraulic communication lines of units and blocks of the machine. Reference weightless calibration machine is equipped with an additional traverse located in the working zone of the power frame, which is rigidly attached by means of columns-racks to the power frame base and forming with lower traverse of the reverse frame an installation zone of calibrated compression force sensors (dynamometers).

EFFECT: simpler design of the device.
