High Pressure Range from 200 to 6,000 bar
The europascal BH4-6000B covers a hydraulic measuring range from:
200 to 6,000 bar
This corresponds to:
20 to 600 MPa
or approximately:
2,900 to 87,000 psi
The maximum pressure is:
6,000 bar / 600 MPa
This extremely high pressure capability makes the BH4-6000B particularly suitable for specialized pressure calibration applications.
Typical devices under test include high-pressure sensors, pressure transducers, high-pressure gauges and measurement systems used in demanding industrial and research applications.
Accuracy of 0.05 %
The europascal BH4-6000B provides a specified accuracy of:
0.05 %
This enables reliable calibration across the very-high-pressure measuring range.
At pressures extending to several thousand bar, the complete measurement uncertainty depends on several influence quantities.
Relevant contributions can include:
- Calibration of the masses
- Effective piston area
- Local gravitational acceleration
- Air buoyancy
- Piston-cylinder temperature
- Pressure deformation
- Pressure coefficient of the piston-cylinder system
- Hydraulic fluid properties
- Hydrostatic head difference
- Repeatability
- Resolution of the device under test
- Environmental conditions
Pressure-dependent deformation of the piston-cylinder assembly becomes particularly important at pressures of several thousand bar and must be considered in the appropriate calibration model.
Fundamental Piston Gauge Measurement Principle
The europascal BH4-6000B Automatic Deadweight Tester is based on the fundamental physical principle of a piston gauge.
The basic relationship is:
p = F / A
where:
p = generated pressure
F = force acting on the piston
A = effective piston area
The gravitational force generated by the calibrated masses is primarily determined by:
F = m × g
where:
m = applied mass
g = gravitational acceleration
The simplified relationship is therefore:
p = (m × g) / A
For precision calibration, the actual pressure calculation includes the relevant corrections associated with the calibrated piston-cylinder system, masses and environmental conditions.
Depending on the calibration model, these can include corrections for local gravity, air buoyancy, piston-cylinder temperature, pressure deformation and hydrostatic head.
The BH4 platform combines this proven physical measurement principle with electronic calculation and operator assistance.
Single-Piston High-Pressure System
The europascal BH4-6000B is designed as a:
single-piston deadweight tester
One precision piston-cylinder system is used to generate the pressure across the specified measuring range.
At these extremely high pressures, the design and characterization of the piston-cylinder assembly are critical to the metrological performance of the pressure balance.
The effective piston area and its pressure-dependent behavior are therefore important parameters in determining the generated reference pressure.
Automatic Pressure Calculation
One of the major advantages of the BH4 platform compared with a conventional manual deadweight tester is its integrated calculation system.
The system assists with:
- Calculation of generated pressure
- Pressure display
- Application of relevant correction parameters
- Different pressure units
- Reduction of manual calculations
- Calibration data handling
This is particularly useful when calibrating at several thousand bar, where accurate evaluation of the piston-cylinder system and environmental quantities is essential.
The automatic calculation functionality reduces operator effort and supports consistent calibration procedures.
Dynamic Piston Position Visualization
Correct piston position is an important requirement for reliable deadweight tester operation.
The BH4 system therefore incorporates:
dynamic piston position visualization
The operator can monitor the piston position during the calibration process and determine whether the piston is operating within the appropriate working position.
This provides greater convenience than purely manual observation and supports repeatable calibration procedures.
Motorized Operation
The automatic BH4 platform incorporates motorized operation of the rotating system.
Rotation of the piston and mass system helps minimize friction effects and supports free movement of the precision piston.
Motorization provides consistent rotation without requiring the operator to rotate the mass system manually throughout the calibration.
This feature is particularly valuable for intensive laboratory use and repetitive calibration procedures.
Integrated Environmental Sensors
Accurate pressure determination with a piston gauge can depend on environmental conditions.
The BH4 concept therefore incorporates sensors for relevant environmental quantities.
These can include:
- Temperature
- Atmospheric pressure
- Relative humidity
Environmental information can be used by the calculation system when determining the reference pressure and applying the appropriate corrections.
This helps reduce manual data entry and supports efficient high-accuracy calibration workflows.
Calibration Result Recording
The europascal BH4-6000B supports the recording of calibration results.
This functionality is particularly useful for professional calibration laboratories performing regular measurements.
Recorded data can support:
- Calibration documentation
- Measurement traceability
- Quality assurance
- Evaluation of devices under test
- Calibration history
- Digital laboratory workflows
The combination of a physical pressure standard and electronic data handling provides significant advantages for modern calibration laboratories.
Computer Communication and Data Transfer
The automatic BH4 system provides communication with a computer.
This allows measurement information to be incorporated into digital calibration workflows.
Computer communication can reduce manual transcription of calibration values and simplify subsequent evaluation and documentation.
For laboratories calibrating a large number of pressure instruments, these functions can provide significant workflow improvements compared with a conventional manual pressure balance.
Different Pressure Units
The integrated calculation functionality also provides flexibility regarding pressure units.
Depending on the selected configuration and application, pressure can be represented in different engineering units.
These can include:
- bar
- MPa
- kPa
- psi
- kg/cm²
This is particularly useful for laboratories working with international customers or pressure instruments specified in different units.
Stainless Steel Calibration Masses
The BH4 series uses:
stainless steel calibration masses
The calibrated masses generate the gravitational force acting on the precision piston.
Their calibration and long-term stability are essential elements of the measurement system because the generated reference pressure is directly related to the applied force.
The BH4 calculation system combines the relevant mass and piston information with environmental and correction parameters to determine the generated reference pressure.
Standard Gravity and Local Gravity
Gravitational acceleration directly influences the force generated by the calibration masses.
The conventional standard value is:
g = 9.80665 m/s²
Actual gravitational acceleration varies according to geographical location.
A pressure balance can therefore be configured or calculated according to the appropriate local gravity value.
This is important in precision pressure metrology because an incorrect gravity value directly influences the calculated reference pressure.
Hydraulic Operation with Oil
The europascal BH4-6000B is a hydraulic pressure balance operating with:
oil
Hydraulic pressure transmission is particularly suitable for the extremely high pressure levels generated by the instrument.
Correct handling of the hydraulic system is essential at these pressures.
The system should be carefully filled and vented, and compatibility between the pressure medium, device under test and all wetted components must be verified.
At pressures up to 6,000 bar, appropriate high-pressure tubing, fittings, adapters and safety equipment must also be selected according to the intended application and maximum operating pressure.
Designed for Very High Pressure Calibration
The BH4-6000B is designed for pressure calibration applications far beyond conventional process pressure ranges.
Typical devices under test can include:
- Ultra-high-pressure sensors
- High-pressure transducers
- High-pressure transmitters
- Precision pressure gauges
- Digital high-pressure gauges
- Reference pressure instruments
- Hydraulic measurement systems
- High-pressure test equipment
- Industrial high-pressure instrumentation
The system is particularly useful where accurate and repeatable reference pressures extending into several thousand bar must be generated regularly.
