Abstract
The utility model relates to a hydraulic comparison type force standard machine, which comprises a standard sensor, a testing host machine, an auxiliary machine, a hydraulic system and an electrical appliance control system. The utility model has the essential technical scheme that an upper plate of the testing host machine is provided with the wide range standard sensor; a replaceable small range standard sensor is installed below the wide range standard sensor; the small range standard sensor is fixed on a transverse plate which is connected with the upper plate through a hanger rod. When the wide range sensor is checked and measured, force is transmitted to the measured sensor through a force transmission mechanism; when the small range sensor is checked and measured, a force transmission rod is taken off, the small range standard sensor is used for replacement and a pressure head of the small range standard sensor directly acts on the measured sensor. The utility model can check and measure the technical performance indices, such as linearity, repeatability, hysteresis, creep deformation, sensitivity, etc., of a weighing sensor of five to one hundred tons and an electronic scale, through one hydraulic comparison type force standard machine. Precision classes are 0.01 and 0.02.
