Compressed Gas
Use of compressed gas can create an environment of propelled foreign matter. Pressure
system safety precautions apply to all ranges of pressure. Care must be taken during
testing to ensure that all hydraulic connections are properly and tightly made prior to
applying pressure. Personnel must wear eye protection to prevent injury.
Heavy Weights
Lifting and movement of heavy weights can create an environment of strain and impact
hazards. Care must be taken during testing to ensure that weight masses are lifted in a
manner that avoids over-reaching or twisting, and that the masses are not dropped.
Personnel must wear reinforced safety shoes to prevent injury.
Personal Protective Equipment
Wear eye protection and reinforced safety shoes approved for the materials and tools
being used.

Operating Principle
Deadweight Testers are the primary standard for pressure measurement. Utilizing the
well-proven Piston-Gauge system, consisting of a vertically mounted, precision lapped
Piston and Cylinder assembly, accurately calibrated weight masses (Force) are loaded on
the piston (Area), which rises freely within its cylinder. These weights balance the
upward force created by the pressure within the system.

Each weight is marked with the tester serial number, and the pressure measured when
placed on a correctly spinning and floating piston. The total pressure measured is the
summation of the weights plus the piston weight carrier assembly.
When the gas pressure within the system balances the combined downward force of the
piston and weights, the piston and weights will float freely and the system is in
equilibrium.
