pump now standard on all

hydraulic models

• Mounted spirit level and

adjustable feet

• High quality screw press

for ﬁne pressure control

• Test station design with

O-rings eliminates the

need for PTFE tape or

wrenches

• Acrylic reservoir provides

visibility of ﬂuid level and

quality

• Improved case with spring-

loaded latches for hood

• Built-in drain plug to

remove old ﬂuid

hinged lid and side han-

dles for easy transport

The P3000 Series is the culmination

of over 50 years experience in the

production and design of primary pres-

sure standards. With features designed

to improve accuracy and performance,

increase reliability and simplify opera-

tion these deadweight testers can be

used to calibrate virtually any pressure

sensing device, including transduc-

ers, transmitters, gauges or pressure

switches.

Each instrument is supplied with

a detachable lid which makes it

neat, compact and easily portable.

The weight masses are stored in a

high-quality case with a self locking

mechanism to protect them during

transit.

All units are provided with an

accredited calibration report, weight

mass 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, operating

ﬂuid (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 calibra-

tion reports.

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. The pressure is measured when placed on a correctly spinning and floating piston.
