ABSTRACT:
A controlled clearance piston load cell consisting of a piston and pressure acketed cylinder that has integral to its structure a system of hydrostatic bearings which provide centering of the piston in the cylinder and alignment of the piston-to-cylinder interface. Also, the geometry of the cylinder and pressure jacket is such as to provide the controlled clearance constriction at a predetermined location. When used with a controlled clearance dead weight piston gage, this self-aligning load cell can be utilized as a primary force standard in the calibration of force-measuring devices.
