Description
Proven primary standard
Pressure balances (dead-weight testers) are the most
accurate instruments available on the market for the
calibration of electronic or mechanical pressure measuring
instruments. The direct measurement of the pressure
(p = F/A), as well as the use of high-quality materials enable
a very small measurement uncertainty, in conjunction with an
excellent long-term stability.
The pressure balance (dead-weight tester) has therefore
been used for years in factory and calibration laboratories in
industry, national institutes and research laboratories.
Hydraulic pressure balance model CPB5800
Basic principle
Pressure is dened as the quotient of force and area. The
core component of the CPB5800 is therefore a very precisely
manufactured piston-cylinder system, onto which a mass
load is applied in order to generate the individual test points.
The mass load is proportional to the target pressure and
this is achieved through optimally graduated masses. As
standard, these masses are manufactured to the standard
gravity (9.80665 m/s²), though they can be adjusted to a
specic location and also UKAS calibrated.
Stand-alone operation
Due to its integrated pressure generation and the purely
mechanical measuring principle, the model CPB5800 is ideal
for on-site use for maintenance and service.

The instrument base model CPB5800
Easy operation
In the stable instrument base, the integrated priming pump
and the 250 ml tank enable large test volumes to be easily
lled and pressurised. For further pressure increases and
ne adjustment, a very precisely controllable spindle pump is
tted, which only runs within the pump body.
As soon as the measuring system reaches equilibrium, there
is a balance of forces between the pressure and the masses
applied. The excellent quality of the system ensures that
this pressure remains stable over several minutes, so that
the pressure value for comparative measurements can be
read without any problems, or also so that more complex
adjustments can be carried out on the test item.
High-performance instrument range
The CPB5800 instrument bases are available in 2 variants:
■
Standard hydraulic base
- up to max. 1,200 bar (16,000 psi)
- with integrated pressure generation through priming
pump and spindle pump
- Pressure transmission medium

As standard, both instrument bases are tted with a
connection for the model CPS5800 piston-cylinder system
with G ¾ male thread.
As an option a M30 x 2 female thread for optional CPS5000
piston-cylinder systems is available.
With the 1,200 bar instrument base (16,000 psi instrument
base), the patented ConTect quick-release mechanism
is available as an option. This enables the piston-cylinder
system to be changed quickly and safely without any tools.
The connection of the test item is made without tools using
a quick connector. Via the freely rotating knurled nut, the test
item can be oriented as required. As standard, a threaded
insert with a G ½ female thread is provided. Other threaded
inserts are available to connect the most common pressure
measuring instruments.

The piston-cylinder system model CPS5800
The CPS5800 piston-cylinder systems are available in two
fundamentally dierent designs, depending on the measuring
range:
■
Single-range piston-cylinder system (for measuring
ranges 120 bar and 300 bar) (1,600 and 4,000 psi)
■
Dual-range piston-cylinder system (for measuring ranges
700 bar, 1,200 bar and 1,400 bar) (10,000, 16,000 and
20,000 psi)
High accuracy over a wide measuring range
The dual-range piston-cylinder system oers two measuring
ranges in one case with automatic measuring range
switching from low-pressure to high-pressure piston. This
provides the user with an extremely exible measuring
instrument that can cover a wide measuring range with high
accuracy, with only one piston-cylinder system and one
mass set. Furthermore, two test points can automatically be
achieved by loading just the one mass.
Both the piston and cylinder are manufactured from
hardened steel or tungsten carbide, respectively. These
pairings of materials have very low pressure and temperature
coecients of expansion, which results in a very good
linearity for the eective area of the piston and a very high
accuracy.
Piston and cylinder are very well protected, against
contact, impacts or contamination from outside, in a solid
stainless-steel/hardened tool steel case. At the same time,
overpressure protection is integrated, which prevents the
piston from being forced out vertically and avoids damage to
the piston-cylinder system in the event of masses removal
under pressure.
The masses are stacked directly onto the piston shaft. This
makes it easier to place the masses on and thus enables a
lower start value.
The overall design of the piston-cylinder system and the very
precise manufacturing of both the piston and the cylinder,
ensure exceptionally low friction force, which results in
excellent operating characteristics with long free-rotation time
and low sink rates. Thus a high long-term stability is ensured.
Therefore, the recommended recalibration interval is two to
ve years dependent on the conditions of use.

The mass set, model CPM5800
The mass set is supplied in a wooden case with a foam
insert. This includes the masses listed in the tables of
masses below, made from non-magnetic stainless steel, and
optimised for everyday use.
For ner increments and for a higher resolution, as an option,
the standard mass sets can be extended by a set of ne
increment masses.
If even smaller intermediate values need to be generated,
using one of the class M1 or F1 set of ne increment masses
from the accessories is recommended.
As an option for the CPS5000 piston-cylinder systems
CPM5000 mass sets are available. For detailed
specications see data sheet CT 31.01.
Tables of masses
Mass set model CPM5800
The following tables show the number of masses within a
mass set with their nominal mass values and the resulting
nominal pressures for the respective measuring ranges.
The masses are manufactured, as standard, to the standard
gravity (9.80665 m/s²) although they can be adjusted for any
local gravity.
Should the instrument not be operated under reference
conditions (ambient temperature 20 °C (68 °F), atmospheric
pressure 1,013 mbar (14.69 psi), relative humidity 40 %),
the measured values must be corrected arithmetically. For

CalibratorUnit model CPU6000
The models of the CPU6000 series are compact tools for use
with a pressure balance (dead-weight tester). In particular
when highly accurate measuring values, with measurement
uncertainties of less than 0.025 %, are required, complicated
mathematical calculations and corrections are necessary.
With the CPU6000 in combination with the CPB-CAL (iPad
app) and/or WIKA-CAL (PC software) all critical ambient
parameters can be registered and automatically corrected.
®
The CPU6000 series is made up of three
instruments
Weather station, model CPU6000-W
The CPU6000-W provides measured values such as
atmospheric pressure, relative humidity and the ambient
temperature of the laboratory environment.
Pressure balance sensor box, model CPU6000-S
The CPU6000-S measures the piston temperature and
displays the oating position of the masses.
Digital multimeter, model CPU6000-M
The CPU6000-M fulls the function of a digital multimeter
and power supply unit when electronic pressure transmitters
must be calibrated.
CPU6000 series and iPad® app CPB-CAL
Typical application
CPB-CAL iPad® app
The iPad
balances (dead-weight testers) or the reference pressure
while taking the measured parameters from the CPU6000
into account. The conversion can be carried out in all
common pressure units. As an additional parameter, the local
gravity can be given for location-independent measurements.
WIKA-CAL PC software - Weight calculator
With the demo version of the WIKA-CAL software and a CPB
series pressure balance (dead-weight tester), the masses to
be applied and the corresponding reference pressure can be
determined. The pressure balance data (dead-weight tester
data) can be entered into the database manually or imported
automatically via an XML le available online.
All ambient parameters and piston temperature can be
entered manually into WIKA-CAL or can be measured
automatically with the CPU6000 series, so that the highest
accuracy can be achieved. WIKA-CAL demo version can be
downloaded free of charge from the WIKA website.
Further specications on the CPU6000 series can be found
in data sheet CT 35.02.
For details of the WIKA-CAL calibration software see data
sheet CT 95.10.
