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.

Pneumatic pressure balance, model CPB5000

Basic principle

Pressure is dened as the quotient of force and area. The

core component of the CPB5000 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 specic

location and also DKD/DAkkS calibrated.

Stand-alone operation

Due to its integrated pressure generation and the purely mechanical measuring principle, the model CPB5000 is ideal for on-site use for maintenance and service.

Easy operation

The pressure setting depends on the instrument version and is either done via an integrated pump or from external pressure supply via a metering valve. For further pressure

increases and ne adjustment, a very precisely controllable spindle pump is tted, which only runs within the pump body.

The piston-cylinder system

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.

Both the piston and cylinder are manufactured from tungsten carbide. This pairing of materials, in comparison to other materials, has very low pressure and temperature

coecients of expansion, which results in a very good linearity for the eective 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 stainlesssteel 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 on a mass carrier, which sits on the piston shaft. The construction of the mass carrier provides a very low centre of gravity for the stacked masses, which minimises both the side thrust on the piston-cylinder system and the friction. For relatively low starting pressures, a lighter aluminium plate can be used instead of the mass carrier.

The overall design of the piston-cylinder system and the very precise manufacturing of both the piston and the cylinder, ensures 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.

Force F

The connection of the piston-cylinder system is a M30 x 2 male thread as standard. The patented ConTect quick-release connector, for easy measuring range changes without the need for tools, is available as an option.

High-performance instrument range

The CPB5000 basic instruments are available in the following three designs:

■

Pneumatic base, low pressure

- up to max. 10 bar (150 psi)

- with integrated pressure generation through priming pump and spindle pump

■

Pneumatic base, high pressure/vacuum

- up to max. 100 bar (1,500 psi)

- connection for external pressure supply or vacuum

■

Pneumatic base with integrated gas to oil separator

- up to max. 400 bar (5,000 psi)

- connection for external pressure supply

- for use with hydraulic piston-cylinder systems with M30 x 2 connection

- test items can be easily, dryly and cleanly calibrated with air

As standard, all basic instruments are tted with a connection

for the piston-cylinder system with a M30 x 2 female thread. The optional, integratable, patented ConTect quick-release connector enables a quick and safe changing of the measuring range without tools. Thus one can build a priceoptimised complete system out of a universal system base

and up to 3 ConTect piston-cylinder systems of dierent

measuring ranges, which can be operated with only one mass set.

The hydraulic measuring ranges of the model CPS5000 piston-cylinder systems can be used on the instrument base of the CPB5800 hydraulic pressure balance. For this, the ConTect quick-release connector is needed.

Tables of masses

The following tables show the number of masses within a mass set with their nominal mass values and the resulting

the relevant corrections must be made, for example with the

CPU6000 CalibratorUnit, see page 9. nominal pressures for the respective measuring ranges. 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 masses are manufactured, as standard, to the standard

gravity (9.80665 m/s²) although they can be adjusted for any

local gravity.

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 fulls 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 specications 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.
