Description
Harwood Engineering's imperial sized deadweight tester's characteristic extreme sensitivity, repeatability, and accuracy results from the minute clearance maintained between the piston and cylinder by means of a variable jacket pressure on the outside of the cylinder producing the close fit of a few millionths of an inch clearance – still with fully free sensitivity and exceptionally small leakage. The overall performance results in a simple evaluation of the effective area and determination of the magnitude of the measured pressure with great accuracy. The Type D models are manufactured for pressures up to 200,000 psi.
