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 pressureswitches.
Each instrument is supplied with adetachable lid that makes it neat, compact and easily portable. The masses
are stored in a high-quality case witha self-locking mechanism to protect
them during transit.
All units are provided with anaccredited calibration certificate,
M14X1.5, M20X1.5, 1/8, 1/4, 3/8, and
1/2 NPT and BSP female adaptors,
operating fluid (where applicable) andspare seals.
The piston/cylinder assemblies aremanufactured to the very highest standards and are supplied with accredited
calibration reports with stated instrumental measurement uncertainties.

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 masses(Force) are loaded on the piston (Area), whichrises freely within its cylinder. These masses
balance the upward force created by the pressure within the system.

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 (standard on thelower pressure models). The hand pump option
is not available on instruments above 500 psi(3.5 MPa).

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.

MassesStandard masses are series 3 non-magnetic
austenitic stainless steel. Each mass is marked
with the serial number of the instrument andthe nominal pressure value relative to the highor low-pressure piston, when applicable. The
masses for the vacuum ranges and the optional
fine increment masses are stainless steel and/oraluminum.

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 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 1/4 inch 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 is recommended. Ten percent above themaximum pressure is required. A built-in handpump is available on some models to generatepressures to 300 psi (2 MPa).
For vacuum requirements, an external
vacuum pump can be connected to the 1/4 inch
port. The built-in hand pump will also generate
up to 90 % vacuum.

PressCal Software
Windows-based software program that allows
users to easily apply all necessary corrections
to enhance the deadweight tester performance.
Calibration details are then stored and/or used
to automatically create a calibration certificate.
The use of PressCal allows for an improved
accuracy of 0.008 %.

Vacuum/Pressure Models

P3000 Series Liquid Lubricated Gas
Operated Models

The combined vacuum/pressure models are
extremely versatile instruments providing
vacuum through 500 psi (3.5 MPa) capacity in
one unit. An optional built-in hand pump canbe installed to generate vacuum (90 %) through300 psi (2 MPa).

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.
