The europascal BH2-6000B Hydraulic Deadweight Tester is a high-performance hydraulic pressure standard developed for precise calibration at extremely high pressures. With a measuring range from 200 to 6,000 bar and a standard accuracy of 0.05 % of reading, the BH2-6000B is designed for professional calibration laboratories, high-pressure measurement applications, research facilities and industrial quality assurance.
For particularly demanding applications, AREMECA specifies an enhanced accuracy of up to 0.02 % of reading on request.
The BH2-6000B is a single-piston deadweight tester. Both the piston and cylinder are manufactured from tungsten carbide, providing the mechanical properties required for pressure generation up to 6,000 bar / 600 MPa.
The instrument operates hydraulically with oil and uses calibrated stainless steel masses to generate a precisely defined force on the piston. The resulting reference pressure is based on the fundamental physical relationship between force and effective piston area.
Unlike the automatic BH4-6000B, the BH2-6000B is configured as a manually operated high-performance pressure balance in its standard configuration. Motorization, piston position visualization and automatic pressure calculation can be added as options.
europascal provides professional support for high-pressure calibration equipment, including system configuration, maintenance and calibration. The europascal calibration service provides calibration solutions for deadweight testers, pressure balances, pressure gauges, pressure sensors, pressure transmitters and other pressure measuring equipment.

Extreme Pressure Range from 200 to 6,000 bar
The europascal BH2-6000B covers a hydraulic measuring range from:
200 to 6,000 bar
This corresponds to:
20,000 to 600,000 kPa
or:
20 to 600 MPa
The manufacturer specifies the imperial range as:
2,000 to 80,000 psi
The maximum pressure is:
6,000 bar / 600 MPa
This exceptionally high pressure capability makes the BH2-6000B suitable for calibrating specialized high-pressure instruments that are far beyond the range of conventional hydraulic deadweight testers.
Accuracy of 0.05 % of Reading
The standard accuracy of the europascal BH2-6000B is:
0.05 % of reading
For more demanding applications, AREMECA specifies:
up to 0.02 % of reading on request
The distinction between standard and optional performance is important when configuring the pressure balance for a specific calibration laboratory.
At pressures extending to 6,000 bar, the complete measurement uncertainty is influenced by several quantities.
Relevant contributions can include:
- Calibration of the mass set
- Effective piston area
- Pressure coefficient
- Pressure deformation
- Piston-cylinder temperature
- Local gravitational acceleration
- Air buoyancy
- Hydraulic fluid properties
- Hydrostatic head
- Repeatability
- Sensitivity
- Resolution and stability of the device under test
The exact uncertainty budget depends on the calibration configuration and procedure.
Physical Piston Gauge Measurement Principle
The europascal BH2-6000B operates according to the proven physical principle of a piston gauge.
The fundamental relationship is:
p = F / A
where:
p = generated pressure
F = force acting on the piston
A = effective piston area
The force generated by the calibration 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 calculation includes the relevant corrections and calibrated characteristics of the piston-cylinder system and mass set.
At pressures up to 6,000 bar, the pressure-dependent behavior of the piston-cylinder system is particularly important.
Single-Piston Configuration
The europascal BH2-6000B is explicitly specified as a:
single-piston deadweight tester
The instrument uses:
1 piston
and:
1 piston-cylinder system
to cover its specified high-pressure measuring range.
This provides a straightforward high-pressure reference system without switching between separate piston assemblies within the specified range.
Tungsten Carbide Piston and Cylinder
A particularly important feature of the BH2-6000B is the material used for its piston-cylinder assembly.
AREMECA specifies:
Piston: tungsten carbide
Cylinder: tungsten carbide
Tungsten carbide provides very high hardness and excellent dimensional stability, properties that are especially important in piston-cylinder systems operating at extremely high hydraulic pressures.
At pressures approaching 6,000 bar, mechanical deformation of the piston-cylinder assembly becomes a significant metrological consideration.
The piston-cylinder design and its calibrated characteristics are therefore central to the performance of the pressure balance.
Hydraulic Operation with Oil
The europascal BH2-6000B operates hydraulically with:
oil
The hydraulic medium transmits the pressure generated by the pressure generator to the piston-cylinder system and the connected device under test.
Correct filling, venting and cleanliness of the hydraulic circuit are important for reliable operation.
All connected tubing, fittings, adapters and devices must be specifically rated for the intended high pressure.
At pressures up to 6,000 bar, suitable high-pressure components and appropriate safety procedures are essential.
Stainless Steel Calibration Masses
The BH2 series uses calibrated:
stainless steel masses
The mass set generates the force acting on the piston.
The manufacturer offers weight sets marked according to the selected pressure unit, such as:
- bar
- kPa
- psi
- kg/cm²
The calibrated mass values, together with the effective piston area and gravitational acceleration, form the physical basis of the generated reference pressure.
Standard or Local Gravity
The force generated by the calibration masses depends directly on gravitational acceleration.
The conventional standard value is:
g = 9.80665 m/s²
AREMECA allows the pressure balance to be configured for standard gravity or a specified local gravity value.
This is important for precision pressure calibration because a relative difference in gravitational acceleration directly affects the force generated by the mass set.
Manual Operation as Standard
The europascal BH2-6000B belongs to the BH2 high-performance deadweight tester series.
In its standard configuration, the mass and piston system is operated manually.
This provides a robust physical pressure standard with a straightforward operating concept.
For laboratories requiring additional operator assistance or automation, the BH2-6000B can be expanded with dedicated options.
Optional OP0004 Motorization
The OP0004 option adds:
- Motorized rotation of the masses
- Piston position visualization
- Indicator lights for operator assistance
Rotation of the piston and mass system helps reduce friction effects and supports free movement of the piston.
Motorization is particularly useful for repetitive calibration procedures and reduces manual intervention.
With OP0004, the instrument weight without the calibration masses increases from approximately 22 kg to 24 kg.
Optional OP0301 Calculator Module
For a higher level of automation, the BH2-6000B can be equipped with:
OP0301
This option adds functions such as:
- Motorization
- Dynamic piston position visualization
- Environmental sensors
- Calculator module
- Automatic pressure calculation
- Automatic display of generated pressure
- Calibration data traceability
- Computer data transfer
The calculator can use relevant parameters to determine the pressure generated by the deadweight tester.
This significantly reduces manual calculation work and allows the BH2-6000B to be incorporated into digitally supported calibration workflows.
Operating Temperature
AREMECA specifies an operating temperature range of:
18 to 28 °C
Temperature is an important influence quantity for a precision piston gauge because thermal expansion affects the effective dimensions of the piston-cylinder system.
For high-quality calibration, the actual piston-cylinder temperature must therefore be appropriately considered.
