The Pressurements 3000 Series isthe culmination of over 50 years experience in the production and designof primary pressure standards. Withfeatures designed to improve accuracy
and performance, increase reliability
and simplify operation these deadweight testers can be used to calibrate
virtually any pressure sensing device,including transducers, transmitters,gauges or pressure switches.
Each instrument is supplied with adetachable lid that makes it neat, compact and easily portable. The weightmasses are stored in a high-quality

case with a self-locking mechanism toprotect them during transit.
All units are provided with a traceable certificate of accuracy, weightmass details, 1/8 inch, 1/4 inch,
3/8 inch and 1/2 inch NPT or BSP
female adaptors, operating fluid (whereapplicable) and spare seals.
The piston/cylinder assemblies
are manufactured to the very highest
standards with certified accuracies
trace-able to international standards
laboratories such as the National
Institute of Standards and Technology(NIST).

Operating principle
Deadweight testers are the primary standard
for pressure measurements. Utilizing the wellproven piston-gauge system consisting of avertically mounted, precision lapped piston andcylinder assembly, accurately calibrated weightmasses (Force) are loaded on the piston (Area),
which rises freely within its cylinder. Theseweights balance the upward force created by
the pressure within the system.
The pressure is measured when placed ona correctly spinning and floating piston. Thetotal pressure measured is the summation of theweights plus the piston weight carrier assembly.

Force

AreaPressure
Pressure =Instrument base
There are four basic variations in the pneumaticoffering; single pressure, single vacuum, dual
vacuum and pressure, and oil-lubricated pneumatically driven high-pressure models. Pressure
or vacuum is generated by an external source oran optional built-in hand pump. The hand pump
option is not available on instruments above
500 psi (35 bar).

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.

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. Vacuum weights and the optional fractional
weights are stainless steel and/or solution heat
treated aluminum.

ForceAreaGravity 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 calibrated to local gravity at no extra cost. If
unspecified, instruments will be calibrated toStandard Gravity at 980.665 cm/s2.

Gas supply
All instruments are fitted with a ⁄ NPT female
external supply port for connection to the gas
supply source. A compressed gas bottle (nitrogen or dry air) fitted with a pressure regulator isrecommended. Ten percent above the maximum
pressure is required. A built-in hand pump isavailable on some models to generate pressures
to 300 psi (20 bar).
For vacuum requirements, an external
vacuum pump can be connected to the ⁄ NPT
port. The built-in hand pump will also generate
up to 90 % vacuum.

Vacuum/Pressure Models

P3000 Series Liquid Lubricated Gas
Operated Models

The combined vacuum/pressure models are
extremely versatile instruments providing
vacuum through 500 psi (35 bar) capacity in
one unit. For added expansion, an additional
low range piston/weight set can be provided
for pressures to 800 inH2O (2 000 mbar). An
optional built-in hand pump can be installed togenerate vacuum (90%) through 300 psi.

The Models P3031 and P3032 feature an oil
lubricated piston/cylinder assembly, which
ensures that the instrument is less susceptible
to performance issues caused by contaminationof the gas supply or the environment in which
the unit is being operated.
The supply gas, via the deadweight testercontrols, is introduced into the piston/cylinderchamber. As the gas acts directly on the surfaceof the oil, there is a rate-less transfer of pressure
within the system.
The instrument is designed to prevent
inadvertent over-filling of the chamber, thus
avoiding contamination of the gassystem. Thereis no physicalbarrier between
the gas and oil
so there is some“oil-mist” transfer potential.
Therefore, we do
not recommend
the standard version for oxygenservice. A special
version of these
instruments
using an oxygencompatible fluid
is available.
