LOAD MEASURING DEVICE WITH A LOAD CELL AND METHOD FOR INTRODUCING A LOADINTO THE LOAD CELL |
摘要 |
A load to be measured is transmitted to a load cell, such as a compression load cell, through a double piston, single cylinder load transmitter that has a pressure chamber between two pistons in the single cylinder. One piston bears against the load. The other piston bears against the load cell to form a floating link between the load and the load cell when a sufficient pressure is introduced into said pressure chamber to prevent unwanted, off-center load application force components from adversely affecting any measured results. Preferably, at least one axially outwardly facing end surface of the piston bearing against the load cell has a curved end surface area. A rocker pin with a pressure controllable variable length may be formed by making both axially outwardly facing end surfaces curved. Several load transmitters may be arranged in parallel to transmit larger loads into a load cell.
