The combination of a low starting pressure of 0.1 bar and an upper limit of 30 bar makes the BA2-30B particularly versatile for laboratories working across low and medium pneumatic pressure ranges.
Ideal for Demanding Calibration Applications
The europascal BA2-30B is designed for professional calibration tasks where pneumatic pressures must be generated precisely and reproducibly.
Its broad range makes the instrument suitable for many common pressure measuring devices.
Typical devices under test include:
- Precision pressure gauges
- Digital pressure gauges
- Reference pressure indicators
- Pressure sensors
- Pressure transmitters
- Pressure transducers
- Pressure switches
- Pneumatic process instruments
- Secondary pressure standards
During calibration, the device under test is connected to the pneumatic pressure system. An external pressure source provides the required pressure, while calibrated masses apply a defined force to the precision piston-cylinder assembly.
When the pneumatic force and the force generated by the masses reach equilibrium, a precisely defined reference pressure is available for comparison with the device under test.
Pressure Range from 0.1 to 30 bar
The europascal BA2-30B covers a measuring range from:
0.1 to 30 bar
This corresponds to:
10 to 3000 kPa
and:
2 to 400 psi
The maximum pressure is therefore 30 bar or 3 MPa.
A major advantage of this range is the low starting pressure of only 0.1 bar combined with an upper limit of 30 bar.
This enables one pressure standard to cover many typical laboratory and industrial calibration tasks.
For applications requiring a lower maximum pressure, the BA2-10B provides a range from 0.15 to 10 bar. For applications extending beyond 30 bar, other BA2 models are available with ranges up to 60, 120 and 200 bar.
Accuracy of 0.01 %
The europascal BA2-30B Pneumatic Deadweight Tester provides a specified accuracy of:
0.01 % of scale
For the pressure measured by the deadweight tester, the manufacturer additionally specifies the uncertainty relationship:
0.0003 + (1 × 10⁻⁴ × P)
where P is expressed in bar.
For a complete calibration, additional measurement uncertainty contributions must also be considered.
These can include:
- Calibration of the masses
- Effective piston-cylinder area
- Local gravitational acceleration
- Air buoyancy
- Piston-cylinder temperature
- Environmental conditions
- Pressure deformation
- Hydrostatic or pneumatic head correction
- Repeatability
- Resolution of the device under test
These contributions should be evaluated according to the required calibration procedure and measurement uncertainty budget.
Fundamental Piston Gauge Measurement Principle
The europascal BA2-30B operates according to the fundamental physical principle of a piston gauge.
Pressure is determined from the force acting on a precisely characterized effective piston area.
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 can be expressed as:
F = m × g
Therefore:
p = (m × g) / A
where:
m = applied mass
g = gravitational acceleration
A = effective piston area
This physically based measurement principle provides an excellent foundation for high-quality pressure calibration.
Precision Single-Piston Design
The europascal BA2-30B uses one piston-cylinder system for its complete pressure range from 0.1 to 30 bar.
The typical piston area is:
78.4825 mm²
According to the manufacturer, the piston is manufactured from treated steel, while the cylinder is made from stainless steel with chrome plating.
The precision piston-cylinder assembly forms the metrological core of the instrument.
Its effective area, together with the force generated by the calibrated masses, determines the generated reference pressure.
The single-piston configuration simplifies operation because there is no need to change between different piston-cylinder systems when working across the specified pressure range.
Pneumatic Operation with Dry Air
The europascal BA2-30B is a pneumatic deadweight tester and operates with dry air.
An external pressure source is required to supply the pneumatic pressure.
The pneumatic operating principle provides an important advantage over hydraulic pressure generation when the device under test should remain free from oil contamination.
This makes the BA2-30B particularly suitable for sensors, transmitters, pressure gauges and other instruments intended for clean pneumatic processes.
Optional oxygen degreasing is also available for applications with corresponding cleanliness requirements.
Flexible Weight Sets and Pressure Units
The BA2-30B can be configured according to the pressure units used in the calibration laboratory.
The principal set of weights can be selected for units such as:
bar
psi
kPa
and other units according to the available configuration.
Intermediate weight sets and additional principal weight sets for different units are also available as options.
This flexibility allows the BA2-30B to be adapted to different industries, calibration procedures and customer requirements.
Standard Gravity and Local Gravity
The generated pressure of a deadweight tester depends directly on the gravitational acceleration acting on its calibrated masses.
The conventional standard value is:
g = 9.80665 m/s²
However, actual gravitational acceleration varies depending on geographical location.
The BA2-30B can therefore be configured for standard gravity or a specified local gravity value.
This is particularly important for precision pressure metrology because the gravitational force directly influences the pressure generated by the deadweight tester.
