The P3000 Series is the culminationof over 50 years experience in theproduction and design of primary pressure standards. With features designed
to improve accuracy and performance,increase reliability and simplify operation these deadweight testers can beused to calibrate virtually any pressure
sensing device, including transducers, transmitters, gauges or pressure
switches.
Each instrument is supplied witha detachable lid which makes it
neat, compact and easily portable.
The weight masses are stored in ahigh-quality case with a self locking
mechanism to protect them duringtransit.
All units are provided with anaccredited calibration report, weightmass details, M14 x 1.5, M20 X 1.5, 1/8
inch, 1/4 inch, 3/8 inch and 1/2 inch
NPT and BSP female adaptors, operatingfluid (where applicable) and spare seals.
The piston/cylinder assemblies
are manufactured to the very highest
standards and are provided standard
with ISO/IEC 17025 accredited calibration reports.

Operating principle
Deadweight testers are the primary standard forpressure measurement. Utilizing the well provenpiston-gauge system consisting of a verticallymounted, precision lapped piston and cylinderassembly, accurately calibrated weight masses(Force) are loaded on the piston (Area), whichrises freely within its cylinder. These weights
balance the upward force created by the pressure within the system.
The pressure is measured when placed ona correctly spinning and floating piston. The
total pressure measured is the summation of theweights plus the piston weight carrier assembly.

ForceArea

Pressure
Pressure =Instrument base
There are three basic variations in the hydraulic offering; single low pressure, single highpressure and dual piston models. Pressure isgenerated and controlled by means of a highquality screw press located on the front of
the tester. A built-in hand pump is included
as standard for all hydraulic models to prime
the system and accommodate large volume
requirements.

Piston/cylinder assemblies
The piston/cylinder assembly is the heart ofeach deadweight tester. They are manufactured
from materials that provide stability, durability,
and low thermal coefficients and distortion. Our
experience and knowledge of piston/cylinder
production and calibration ensure the precisionand performance required for today’s demanding calibration requirements.

Force
Area

Weight masses
Standard weight masses are series 3 nonmagnetic austenitic stainless steel. Each mass
is marked with the serial number of the instrument and the nominal pressure value relative tothe high or low-pressure piston, when applicable. Optional fractional weights are stainlesssteel and/or solution heat treated aluminum.

Gravity correction
Gravity varies significantly with geographicallocation and this variation has a direct effecton the force of the weights and the accuracyof the deadweight tester. Each instrument canbe trimmed to local gravity at no extra cost. If
unspecified, instruments will be calibrated toStandard Gravity at 980.665 cm/s2.
