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.

Stand-alone operation

Due to its integrated pressure generation and the pure mechanical measuring principle, the model CPB5600DP is ideal for on-site use for maintenance and service.

Pressure balance for dierential pressure, model CPB5600DP

Basic principle

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

core component of the CPB5600DP 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.

Easy operation

The pressure setting depends on the instrument design and is either done via an integrated pump or from external

pressure supply via a metering valve. For ne adjustment, a very precisely controllable spindle pump is tted, with a

precision spindle running within it.

The piston-cylinder system

As soon as the measuring system reaches equilibrium, there is a balance of forces between the pressure and the masses. 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 stainless-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 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 inter-

val is two or ve years depending on the conditions of use.

High-performance instrument range

The CPB5600DP instrument bases are available in the following four designs:

■

Pneumatic base

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

- with integrated pressure generation through priming pump and spindle pump

- connection for external pressure supply

■

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

■

Hydraulic base

- up to max. 1,000 bar (14,500 psi)

- with integrated pressure generation through priming pump and spindle pump

- special designs available to 1,200 bar (17,400 psi)

■

Hydraulic high-pressure base

- up to max. 1,600 bar (23,200 psi)

- with integrated pressure generation through priming pump and spindle pump

- for use with hydraulic high-pressure piston-cylinder systems with M30 x 2 connection with sealing cone

The instruments include the components of two pressure

Force F

balances in one case. For the calibration of dierential pressure gauges under a static pressure, the two systems are separated by a by-pass valve.

One of the systems is used to generate the static pressure

with the second system generating the dierential pressure

(incl. static pressure). It is recommended that one of the sets of ne increment masses is used for this (see accessories).

The instrument bases, pneumatic to 100 bar (1.450 psi) and

hydraulic, are tted with the patented ConTect quick-release

mechanism. This enables a quick and safe replacement of the piston-cylinder system without any tools. The pneumatic

Eective area A

instrument version with separator is tted with a connection for the piston-cylinder system with M30 x 2 female thread

and the hydraulic high-pressure base version is tted with a

M30 x 2 female thread with sealing cone.

Tables of masses

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 relevant corrections must be made, for example with the CPU6000 CalibratorUnit, see page 10.

Lower limiting value of the measurement uncertainty

1) Measuring range = static pressure + dierential pressure

2) Theroretical starting value; corresponds to the pressure value generated by the piston (by its own weight). To optimise the operating characteristics more masses should be loaded.

3) The smallest pressure change value that can be achieved based on the standard mass set. To reduce this, a set of ne increment masses is also available.

4) The sensitivity is the threshold of the measuring system. It is the pressure value of the smallest mass load, which brings the piston-cylinder system clearly and reproducibly out of balance.

5) Measurement uncertainty assuming reference conditions (ambient temperature 20 °C (68 °F), atmospheric pressure 1,013 mbar (14.69 psi), relative humidity 40 %). For operation without a CalibratorUnit, corrections must be made if required.

6) The accuracy of the dierential pressure is determined in accordance with the following calculation basis (see page 9).

Calculation of the measurement uncertainty

The accuracy of the dierential pressure is the quadratic sum of the percentage of static pressure u and the percentage of the dierential pressure value u

individual components are taken into account. What is calculated is the expanded measurement uncertainty U (k = 2), in which the measurand lies with a probability of 95 %.

The measurement uncertainty is calculated as per the following equation:

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.
