Piston Gauges as a Precise-Measuring Instrument

Posted by & filed under Technical Papers.

The errors which must be considered for accurate measurements of pressure with piston gauges are discussed. Harwood’s unique design of piston gauge which permits the operator to control the clearance between the piston and cylinder at any operating pressure is described. Instrument errors are thus substantially reduced, particularly those resulting from elastic distortion.  A check list […]
