发明名称 Method and apparatus for calibrating and/or checking of load cells
摘要 A method and an apparatus for calibrating and/or testing of load cells of heavy duty weighing systems use a force transmission device being self-adjustable without friction and having a force transmission ratio in the range of 1:50 to 1:5000 and is adapted to be placed onto a force introduction member. The load cell interposed between said force introduction member and a base may be calibrated by connecting said force transmission device through said force introduction member to said base and by applying varying calibration standards at the force introduction side of the force transmission device.
