ABSTRACT:
A load cell mass comparator wherein a pressure compensated load cell is connected at its upper end to a floating plate through a self-aligning coupling, such as, a universal joint assembly. The floating plate is slidably mounted on a plurality of guide rods extending between fixed upper and lower plates. A spring assembly and shock absorber are mounted between the upper fixed plate and floating plate. The lower end of the load cell is connected to the mass to be calibrated through a universal joint, thrust bearing, and spherical load stop bearing. The construction and arrangement of the components in the load cell mass comparator provides an instrument employed heretofore in a laboratory environment to a commercial environment where masses in the range of 1 to 10,000 pounds can be compared and calibrated.
