The europascal BA2-1VB Vacuum Deadweight Tester is a high-performance pneumatic pressure standard specifically designed for precise vacuum and negative gauge pressure calibration. With a measuring range from -15 to -900 mbar, equivalent to -1.5 to -90 kPa, and an accuracy of 0.03 %, the BA2-1VB provides a reliable solution for professional calibration laboratories, industrial metrology, quality assurance, research and development.
As the dedicated vacuum model within the europascal Aremeca BA2 series, the BA2-1VB extends the proven deadweight tester principle into the negative gauge pressure range. This makes it particularly suitable for calibrating vacuum gauges, pressure sensors, pressure transmitters and other instruments operating below atmospheric pressure.
The BA2 series combines a fundamental physical pressure measurement principle with robust mechanical construction and flexible laboratory operation. Instead of relying exclusively on an electronic pressure reference, a deadweight tester generates pressure through the relationship between force and the effective area of a precision piston-cylinder assembly.
europascal supports customers with the selection, configuration, maintenance and calibration of professional pressure standards. The europascal calibration service provides professional calibration solutions for pressure measuring instruments, reference standards and other calibration equipment.

Ideal for Demanding Calibration Applications
The europascal BA2-1VB is particularly suitable for applications in which instruments must be calibrated in the vacuum or negative gauge pressure range.
Typical devices under test include:
- Vacuum pressure gauges
- Digital vacuum gauges
- Negative gauge pressure indicators
- Vacuum transmitters
- Pressure transmitters
- Pressure sensors
- Pressure transducers
- Pneumatic reference instruments
- Industrial vacuum measuring equipment
The measuring range begins at -15 mbar and extends to -900 mbar.
This makes the BA2-1VB particularly useful for laboratories that calibrate instruments operating below atmospheric pressure without requiring high-vacuum measurement technology.
Vacuum Range from -15 to -900 mbar
The europascal BA2-1VB covers a negative gauge pressure range from:
-15 to -900 mbar
or:
-1.5 to -90 kPa
The BA2-1VB therefore operates relative to atmospheric pressure.
At -900 mbar gauge pressure, the pressure is approximately 900 mbar below the surrounding atmospheric pressure. The corresponding absolute pressure depends on the actual atmospheric pressure at the time of measurement.
This distinction is important in pressure metrology because vacuum can be specified as either negative gauge pressure or absolute pressure.
The BA2-1VB is specified as the vacuum model of the BA2 pneumatic deadweight tester series and is designed for negative gauge pressure calibration.
Fundamental Piston Gauge Measurement Principle
The europascal BA2-1VB Vacuum Deadweight Tester is based on the physical piston gauge principle.
A piston-cylinder system with a precisely characterized effective area interacts with calibrated masses and the pneumatic pressure system.
The fundamental pressure relationship is:
p = F / A
where:
p = pressure
F = force
A = effective piston area
The gravitational force generated by calibrated masses is determined primarily by:
F = m × g
where:
m = mass
g = gravitational acceleration
This physical relationship provides the metrological foundation of a deadweight tester.
For high-quality measurements, additional influence quantities must also be considered. These can include local gravitational acceleration, air buoyancy, temperature, the effective piston-cylinder area and environmental conditions.
This fundamental measurement principle makes the BA2-1VB an excellent reference solution for professional vacuum calibration.
Dedicated Vacuum Model of the BA2 Series
The europascal Aremeca BA2 product family covers both positive pneumatic pressure and vacuum applications.
The BA2-1VB is specifically designed for vacuum calibration.
Its specified range is:
-15 to -900 mbar
This distinguishes it from the BA2-1B, which is designed for positive gauge pressures from 15 to 1000 mbar.
The two instruments therefore complement each other particularly well in laboratories requiring both positive and negative low-pressure calibration.
The BA2-1VB covers pressures below atmospheric pressure, while the BA2-1B covers positive pressures up to 1 bar.
Pneumatic Vacuum Calibration
The europascal BA2-1VB belongs to the pneumatic BA2 deadweight tester family.
Pneumatic operation offers several advantages for suitable pressure measuring instruments.
Unlike hydraulic deadweight testers, the system does not require hydraulic oil to be introduced into the measurement circuit of the device under test.
This is particularly useful for sensitive pneumatic pressure sensors, transmitters and gauges where contamination with hydraulic fluid must be avoided.
Clean pneumatic operation is therefore an important advantage when calibrating instruments intended for gas pressure or vacuum applications.
BA2-1VB and BA2-1B
The BA2-1VB and BA2-1B are complementary low-pressure models within the europascal Aremeca BA2 family.
| Model | Application | Measuring Range |
|---|---|---|
| BA2-1VB | Vacuum / negative gauge pressure | -15 to -900 mbar |
| BA2-1B | Positive gauge pressure | 15 to 1000 mbar |
Both models provide specialized coverage close to atmospheric pressure.
For laboratories calibrating instruments on both sides of atmospheric pressure, the combination of these two models can provide an effective solution.
The BA2-1VB is optimized for negative gauge pressure, while the BA2-1B provides positive pressure generation up to 1 bar.
Flexible Weight Sets and Pressure Units
Calibration laboratories may work with different pressure units depending on industry, customer requirements and existing procedures.
The BA2 product family can therefore be configured with weight sets corresponding to different pressure units.
This makes it possible to configure the system according to the pressure units commonly used in the laboratory.
Using weights directly associated with the desired pressure unit can simplify operation and reduce the need for manual unit conversion during calibration procedures.
Additional configurations can be discussed with europascal according to the individual application.
Standard Gravity and Local Gravity
The generated pressure of a deadweight tester depends on the gravitational force acting on the calibrated masses.
The conventional standard gravitational acceleration is:
9.80665 m/s²
However, actual gravitational acceleration varies according to geographical location.
For high-quality pressure measurements, this difference can become relevant.
The europascal Aremeca BA2 series can therefore be configured according to standard gravity or a customer-specified local gravity value.
This enables the pressure standard to be adapted to the location where it will actually be operated.
