Measuring Range from 40 to 3,000 bar
The europascal BH2-3000B covers a hydraulic measuring range from:
40 to 3,000 bar
This corresponds to:
4 to 300 MPa
and:
4,000 to 300,000 kPa
AREMECA specifies the imperial measuring range as:
600 to 44,000 psi
The maximum pressure is therefore:
3,000 bar / 300 MPa
This wide pressure range makes the BH2-3000B particularly suitable for laboratories that need to calibrate both medium-high and very high-pressure measuring instruments with a single pressure balance.
Accuracy of 0.02 % of Reading
The standard accuracy of the europascal BH2-3000B is:
0.02 % of reading
For applications with more demanding metrological requirements, AREMECA specifies enhanced performance:
up to 0.008 % on request
The specification as a percentage of reading is particularly advantageous for an instrument with such a wide measuring range.
The actual measurement uncertainty achieved during calibration additionally depends on the individual calibration certificate, operating conditions and complete uncertainty budget.
Physical Piston Gauge Measurement Principle
The europascal BH2-3000B High Pressure Deadweight Tester operates according to the physical piston gauge principle.
The fundamental 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 pressure relationship is therefore:
p = (m × g) / A
This direct physical relationship between mass, gravity and effective piston area is the basis of deadweight tester pressure generation.
For precision calibration, additional correction quantities are considered according to the calibration certificate and operating conditions.
Single-Piston Configuration
The europascal BH2-3000B is designed as a:
single-piston deadweight tester
The instrument incorporates:
1 precision piston-cylinder system
The complete specified measuring range from 40 to 3,000 bar is covered with this single piston configuration.
This provides straightforward operation because there is no need to switch between separate low-pressure and high-pressure piston-cylinder assemblies within the specified range.
Tungsten Carbide Piston and Cylinder
The BH2-3000B uses:
Piston: tungsten carbide
Cylinder: tungsten carbide
Tungsten carbide provides high hardness, excellent wear resistance and good dimensional stability.
These characteristics are particularly important for a precision piston-cylinder assembly operating at pressures up to:
3,000 bar / 300 MPa
The effective piston area is one of the most important metrological parameters of a deadweight tester because it directly determines the generated pressure.
Hydraulic Operation with Oil
The europascal BH2-3000B is a hydraulic pressure balance operating with:
oil
Hydraulic operation is particularly suitable for generating very high pressures because liquids have relatively low compressibility compared with gases.
Correct filling and venting are important for stable pressure generation.
Trapped gas can increase settling times and affect pressure stability. Cleanliness is also important because contamination can adversely affect precision hydraulic components.
Compatibility between the hydraulic medium and the connected device under test should always be verified before calibration.
High-Pressure Calibration up to 300 MPa
A maximum pressure of 3,000 bar corresponds to:
300 MPa
At these pressures, every pressure-containing component of the calibration setup must be suitable for the maximum applied pressure.
This includes:
- High-pressure tubing
- Fittings
- Adapters
- Valves
- Seals
- Pressure generator
- Device under test
- Associated safety components
The system must be completely depressurized before hydraulic connections are changed.
Measurement Uncertainty Contributions
The complete measurement uncertainty of a calibration does not depend only on the stated accuracy of the pressure balance.
Relevant influence quantities can include:
- Calibration uncertainty of the masses
- Effective piston area
- Pressure coefficient
- Elastic deformation of the piston-cylinder assembly
- Local gravitational acceleration
- Air buoyancy
- Piston-cylinder temperature
- Thermal expansion
- Hydraulic fluid properties
- Hydrostatic head difference
- Repeatability
- Sensitivity
- Pressure stability
- Resolution of the device under test
- Environmental conditions
At pressures up to 300 MPa, pressure-related changes in the effective piston area can become particularly important.
The final measurement uncertainty should therefore be determined from the actual calibration data and calibration procedure.
Stainless Steel Calibration Masses
The BH2 series uses:
stainless steel calibration masses
The calibrated masses generate the gravitational force acting on the piston.
Together with the effective piston area and gravitational acceleration, they determine the generated reference pressure.
The mass sets are ergonomically designed for loading onto the pressure balance.
Different pressure units can be selected according to the required configuration.
Manual Mass Rotation as Standard
The BH2 platform uses manual rotation of the masses as standard.
Rotation of the piston helps minimize friction effects between the piston and cylinder and supports stable operation of the precision piston-cylinder assembly.
For laboratories performing frequent or repetitive calibration sequences, motorized rotation is available as an option.
Standard or Local Gravity
The force generated by calibration masses depends directly on gravitational acceleration.
The conventional standard value is:
g = 9.80665 m/s²
Actual gravitational acceleration varies geographically.
The BH2-3000B can therefore be configured for:
standard gravity
or:
customer-specific local gravity
Using the correct gravity value is important for precision pressure calibration because a relative change in gravitational acceleration directly changes the force produced by the calibration masses.
Environmental Conditions
AREMECA specifies an operating temperature range of:
18 to 28 °C
The manufacturer specifies calibration reference conditions including:
Temperature: 20 °C
Atmospheric pressure: 1013.25 hPa
Relative humidity: 50 %
Gravitational acceleration: 9.80665 m/s²
If the instrument is used under different environmental conditions, the generated pressure should be calculated using the relevant correction quantities.
Leveling and Installation
Correct leveling is important for reliable piston gauge operation.
The BH2 platform therefore incorporates:
- Leveling bubble
- Adjustable feet
The pressure balance should be installed on a stable work surface and carefully leveled before calibration.
Correct leveling helps the piston move vertically and minimizes unwanted lateral forces within the piston-cylinder assembly.
Device Under Test Connection
The BH2 series provides a connection for the instrument under test using:
swivel G1/2 HP
Other fittings are available as options.
The appropriate adapter must always be selected according to the pressure rating, thread type and sealing system of the device under test.
At pressures up to 3,000 bar, the pressure rating of every fitting and adapter must be verified before operation.
Instrument Weight
The standard BH2-3000B weighs approximately:
22 kg without calibration masses
When equipped with option OP0004 or OP0301, AREMECA specifies approximately:
24 kg without calibration masses
The total system weight additionally depends on the selected calibration mass set.
Optional OP0004 Motorization
The europascal BH2-3000B can be equipped with:
Option OP0004
This provides:
- Motorized rotation of the masses
- Piston position visualization using indicator lights
Motorized rotation reduces the need for manual intervention during repetitive calibration procedures.
Piston position visualization assists the operator in maintaining the piston within the correct working position.
Optional OP0301 Calculator Module
For more advanced calibration workflows, the BH2-3000B can be equipped with:
Option OP0301
This option provides additional functions such as:
- Motorized operation
- Dynamic piston position visualization
- Environmental sensors
- Automatic pressure calculation
- Automatic pressure display
- Consideration of environmental quantities
- Calibration data traceability
- Computer data transfer
This allows the standard manually operated BH2 platform to be expanded toward a more automated calibration workflow.
