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 pneumatic measuring principle is particularly useful when the device under test should remain free from hydraulic calibration media.
This makes the BA4-60B an excellent pressure standard for laboratories calibrating instruments intended for air, gas or clean pneumatic applications.
Pressure Range from 0.5 to 60 bar
The europascal BA4-60B covers a measuring range from:
0.5 to 60 bar
This corresponds to:
50 to 6000 kPa
or:
5 to 800 psi
The maximum pressure is therefore:
60 bar / 6 MPa
This range covers many common industrial and laboratory pneumatic calibration applications.
Within the automatic BA4 product family, the BA4-60B provides the lowest pressure range. For applications requiring higher pressures, the BA4-120B and BA4-200B extend the automatic pneumatic deadweight tester concept to 120 bar and 200 bar.
Accuracy up to 0.005 %
The europascal BA4-60B Automatic Deadweight Tester is designed for high-accuracy pressure calibration.
The BA4 automatic series provides an accuracy of up to:
0.005 %
For the BA4-60B, the specified pressure measurement uncertainty is:
0.0002 + (5 × 10⁻⁵ × P)
where P is expressed in bar.
The complete measurement uncertainty of an actual calibration additionally depends on the configuration of the system, calibration data, environmental conditions and the device under test.
Relevant influence quantities can include:
- Calibration of the masses
- Effective piston-cylinder area
- Local gravitational acceleration
- Air buoyancy
- Piston temperature
- Atmospheric pressure
- Humidity
- Pressure deformation
- Pressure head differences
- Repeatability
- Resolution of the device under test
A major advantage of the BA4-60B is that several important environmental quantities are measured automatically and included in the pressure calculation.
Fundamental Piston Gauge Measurement Principle
Despite its advanced electronic functions, the europascal BA4-60B remains based on the fundamental physical measurement principle of a piston gauge.
Pressure is generated by applying a precisely defined force to a characterized effective piston area.
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 calibrated masses can be expressed as:
F = m × g
where:
m = applied mass
g = gravitational acceleration
The simplified relationship therefore becomes:
p = (m × g) / A
For high-accuracy pressure measurements, additional corrections must be considered.
The integrated calculator of the BA4-60B assists with these calculations and automatically displays the pressure generated by the deadweight tester.
Automatic Pressure Calculation
One of the most important advantages of the europascal BA4-60B is its integrated calculator.
The system automatically displays the pressure generated by the deadweight tester according to relevant physical quantities.
The BA4-60B incorporates measurements for:
- Piston temperature
- Atmospheric pressure
- Relative humidity
These values can be used by the integrated calculation system when determining the generated reference pressure.
This reduces the amount of manual calculation required by the operator and simplifies everyday calibration work.
It also reduces the risk of transcription or calculation errors when environmental corrections must be considered.
Dynamic Piston Position Visualization
Correct piston position is essential during operation of a deadweight tester.
The BA4-60B therefore provides dynamic visualization of the piston position.
Instead of relying solely on manual observation, the operator receives direct information about the current piston position.
This helps identify the correct measurement condition and provides valuable operator assistance during calibration.
The function is particularly useful during repetitive calibration work and when multiple calibration points must be generated efficiently.
Motorized Weight Rotation
The BA4-60B includes motorized rotation of the weights.
An electric motor rotates the mass system during operation.
Rotation of the piston and applied masses is an important part of the piston gauge measurement process because it helps reduce friction effects and supports stable operation of the piston-cylinder assembly.
Automatic rotation eliminates the need for the operator to manually rotate the weights during each calibration point.
This feature distinguishes the BA4 automatic series from more manually operated deadweight tester configurations and contributes to efficient laboratory operation.
Environmental Measurement and Compensation
High-accuracy pressure generation depends on more than the nominal values of the piston area and applied masses.
Environmental conditions also influence the measurement result.
The europascal BA4-60B therefore incorporates environmental measurements directly into the system.
The specified measurement functions include:
Temperature measurement: precision approximately ±0.1 °C
Atmospheric pressure measurement: precision approximately ±1 hPa
Humidity measurement: precision approximately ±10 %
These measured quantities are available to the integrated calculator for determining the generated pressure.
This integrated approach is particularly useful for professional laboratories because important correction quantities are available directly at the pressure standard.
Pneumatic Operation with Air or Nitrogen
The europascal BA4-60B is a pneumatic deadweight tester.
The operating medium is:
clean and dry compressed air
or:
nitrogen
The instrument must be connected to a suitable external regulated pressure source.
Pneumatic operation provides a significant advantage when calibrating pressure measuring instruments that should not come into contact with hydraulic oil.
The piston system itself incorporates lubrication, but the calibration pressure medium remains pneumatic.
This makes the BA4-60B suitable for precision pressure gauges, sensors, transmitters and other devices intended for gas applications.
Precision Single-Piston System
The BA4-60B uses a single precision piston-cylinder system across its complete measuring range.
The typical piston area is:
78.4825 mm²
The single-piston design simplifies operation and avoids the need to change between different piston-cylinder systems during normal use.
The piston-cylinder assembly represents the central metrological element of the deadweight tester and provides the effective area required to convert the force generated by the calibrated masses into pressure.
Multiple Pressure Units
Another advantage of the automatic calculation system is the possibility of working with different pressure units.
The integrated calculator allows the generated pressure to be displayed in different measurement units while using the same physical set of weights.
Depending on the required configuration, pressure values can therefore be handled in units such as:
bar
kPa
psi
and other supported pressure units.
This provides additional flexibility for calibration laboratories working with instruments from different industries and international markets.
Computer Connection and Data Transfer
The BA4-60B provides a connection for transferring data to a computer.
This feature supports traceability and enables measurement information to be incorporated into digital calibration workflows.
Compared with a purely mechanical deadweight tester, the combination of physical pressure generation, integrated environmental measurements, automatic calculation and electronic data transfer can significantly simplify calibration documentation.
This makes the BA4-60B particularly attractive for laboratories aiming to improve efficiency and reduce manual data handling.
