With its maximum pressure of 200 bar, the BA2-200B enables laboratories to perform demanding high-pressure calibrations pneumatically rather than changing to a hydraulic pressure medium.

Ideal for Demanding Calibration Applications

The europascal BA2-200B is designed for professional calibration applications requiring accurately generated pneumatic reference pressures at pressures up to 200 bar.

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
  • Industrial pressure measuring equipment

The ability to generate pneumatic pressures up to 200 bar is particularly useful for laboratories calibrating gas-pressure instruments that must remain free from hydraulic oil.

This makes the BA2-200B an excellent solution for specialized pneumatic calibration workloads.

Pressure Range from 2.5 to 200 bar

The europascal BA2-200B covers a measuring range from:

2.5 to 200 bar

This corresponds to:

250 to 20,000 kPa

or:

25 to 3,000 psi

The maximum pressure is therefore:

200 bar / 20 MPa

This makes the BA2-200B the highest-range pneumatic model in the current BA2 High Performance series.

For laboratories requiring lower pressures, the BA2 family provides additional models with maximum pressures of 1, 10, 30, 60 and 120 bar, as well as a dedicated vacuum version.

Accuracy of 0.01 %

The europascal BA2-200B Pneumatic Deadweight Tester provides a specified accuracy of:

0.01 % of scale

The manufacturer additionally specifies the uncertainty of the pressure measured by the deadweight tester as:

0.002 + (1 × 10⁻⁴ × P)

where P is expressed in bar.

The complete measurement uncertainty of an actual calibration also depends on additional influence quantities.

These can include:

  • Calibration of the masses
  • Effective piston-cylinder area
  • Local gravitational acceleration
  • Air buoyancy
  • Piston-cylinder temperature
  • Atmospheric conditions
  • Pressure deformation
  • Pressure head differences
  • Repeatability
  • Resolution of the device under test

These influence quantities should be considered when establishing the measurement uncertainty budget for professional or accredited calibration procedures.

Fundamental Piston Gauge Measurement Principle

The europascal BA2-200B operates according to the fundamental physical principle of a piston gauge.

Pressure is derived from a precisely defined force acting on a piston with a characterized effective area.

The basic relationship is:

p = F / A

where:

p = generated pressure
F = force acting on the piston
A = effective piston area

The force generated by 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

For high-accuracy pressure calibration, additional corrections are applied according to the calibration data and operating conditions of the piston-cylinder system.

The physical measurement principle provides excellent long-term stability and makes the BA2-200B a high-quality reference standard for professional pressure metrology.

Precision Single-Piston Design

The europascal BA2-200B uses one precision piston-cylinder system across its complete measuring range from 2.5 to 200 bar.

The typical piston area is:

15.6966 mm²

According to the manufacturer specification, the piston is manufactured from tungsten carbide, while the cylinder is made from treated steel.

The small effective piston area enables high pneumatic pressures to be generated using practical calibrated mass loads.

The piston-cylinder assembly represents the central metrological component of the deadweight tester. Its calibrated effective area, together with the force generated by the masses, determines the generated reference pressure.

The single-piston configuration also provides straightforward operation across the complete specified pressure range.

Pneumatic Operation with Air or Nitrogen

The europascal BA2-200B operates pneumatically using:

clean and dry compressed air

or:

nitrogen

This provides an important advantage over hydraulic pressure calibration when the device under test must remain free from oil contamination.

The BA2-200B is therefore particularly suitable for pressure sensors, transmitters, pressure gauges and other instruments intended for clean gas applications.

A suitable external pressure supply must provide the pressure required for operation.

The system also incorporates a piston lubrication system using H15 oil with a specified density of approximately 845 kg/m³.

The lubricant is used within the piston lubrication system. The calibration pressure medium itself remains pneumatic.

Flexible Weight Sets and Pressure Units

The europascal BA2-200B can be configured with principal weight sets for different pressure units.

Available configurations include units such as:

bar

psi

kPa

and other units according to the selected configuration.

Intermediate weight sets and additional principal weight sets for different pressure units are also available.

This flexibility enables the BA2-200B to be adapted to the requirements of different laboratories, industries and calibration procedures.

Standard Gravity and Local Gravity

The pressure generated by a deadweight tester depends directly on gravitational acceleration.

The conventional standard gravitational acceleration is:

g = 9.80665 m/s²

However, actual gravitational acceleration varies according to geographical location.

Because the force generated by the masses is directly proportional to gravity, this effect becomes important in high-accuracy pressure metrology.

The BA2-200B can therefore be configured for standard gravity or for a customer-specified local gravity value.

This allows the mass set to be optimized for the actual installation location of the pressure standard.

Optional Motorization and Piston Position Visualization

The europascal BA2-200B can be equipped with option OP0004.

This option provides motorized rotation of the masses together with visualization of the piston position using indicator lights.

Correct piston rotation and positioning are important during operation of a deadweight tester.

Motorized rotation reduces manual intervention during repetitive calibration procedures, while the position indicators help the operator maintain the piston within its appropriate operating range.

This option can therefore improve convenience and efficiency during routine calibration work.

Optional Automatic Pressure Calculation

For laboratories requiring additional digital functionality, the BA2-200B can be equipped with option OP0301.

This calculator module combines motorization and piston position visualization with sensors and automatic calculation of the pressure generated by the deadweight tester.

The calculation can consider environmental quantities such as:

  • Temperature
  • Atmospheric pressure
  • Humidity

The system also provides data transfer to a computer.

This supports improved traceability and can simplify the preparation of calibration documentation.

The option enables the fundamental physical measurement principle of a deadweight tester to be combined with modern digital calibration workflows.
