Fundamental Piston Gauge Measurement Principle
The europascal EP-BG10 operates according to the fundamental piston gauge principle.
A piston-cylinder assembly with a precisely known effective cross-sectional area A is loaded with calibrated masses m. Pneumatic pressure is applied below the piston until equilibrium is reached between the generated pressure force and the gravitational force produced by the masses.
The basic relationship is:
p = (m × g) / A
where:
p = generated pressure
m = applied mass
g = local acceleration due to gravity
A = effective piston-cylinder area
The generated reference pressure is transferred directly to the device under test. The value indicated by the test instrument can then be compared with the reference pressure generated by the EP-BG10.
This fundamental principle makes piston gauges particularly valuable as reference standards in pressure metrology. The EP-BG10 datasheet explicitly describes it as a primary standard and specifies its use for calibrating pressure gauges, pressure transmitters, pressure switches and secondary standards.

Pneumatic Pressure Range from 0.1 to 10 bar
The europascal EP-BG10 Pneumatic Piston Gauge covers a measuring range from 0.1 bar to 10 bar.
This range makes the system suitable for a wide variety of low and medium pneumatic pressure calibration applications.
The pressure is established by placing the appropriate combination of weights on the piston-cylinder unit.
The standard mass distribution provides multiple pressure increments and allows the operator to build the desired reference pressure systematically.
The supplied weights provide nominal increments corresponding to different pressure levels, while the piston itself contributes an additional pressure component.
Optional fine weights can be used where smaller pressure increments are required.
Precision Piston-Cylinder Unit
The piston-cylinder unit is the central metrological component of the europascal EP-BG10.
For the 10 bar measuring range, the piston-cylinder unit is manufactured from stainless steel, with an aluminum top plate.
The specified repeatability is:
4 × 10⁻⁵ × p
The piston is air-lubricated, eliminating the need for an oil lubrication system within the piston-cylinder assembly. The specified pressure medium is clean and dry gas, for example nitrogen or air. EP-BG10 pneumatic testing devic…
This pneumatic design is especially useful for instruments that should not be contaminated with hydraulic calibration fluids.
Manual Pressure Generation with Fine Adjustment
Pressure generation is performed using a manual pump system.
The EP-BG10 includes a pressure pump type ADT914A with the required accessories. EP-BG10 pneumatic testing devic…
The lever pump allows pressure to be generated efficiently, while the adjusting wheel provides fine pressure control.
During calibration, the operator increases or decreases the pressure until the piston reaches equilibrium with the applied masses.
This provides direct visual and mechanical confirmation that the required reference pressure has been established.
The combination of manual pressure generation and precision fine adjustment makes the EP-BG10 independent of complex automated pressure generation systems.
Weight Set for Pressure Generation
The supplied weight set is manufactured from burnished steel with a specified density of 7200 kg/m³.
According to the EP-BG10 datasheet, the standard mass distribution includes:
| Quantity | Nominal increment | Combined nominal value | Approx. pressure |
|---|---|---|---|
| 6 pcs. | 1.25 kg/cm² | 7.50 kg/cm² | 7.35 bar |
| 4 pcs. | 0.5 kg/cm² | 2.00 kg/cm² | 1.96 bar |
| 4 pcs. | 0.25 kg/cm² | 1.00 kg/cm² | 0.98 bar |
| 2 pcs. | 0.05 kg/cm² | 0.10 kg/cm² | 0.1 bar |
The complete weight configuration provides 10.60 kg/cm² plus piston weights, corresponding to approximately 10.4 bar plus 0.07 bar according to the datasheet. EP-BG10 pneumatic testing devic…
Fine weights made from light metal are optionally available.

Easy and Reliable Calibration Procedure
Operation of the europascal EP-BG10 follows a straightforward calibration sequence.
First, the clean device under test is mounted on the test port and tightened by hand. The required weights are then placed on the piston-cylinder assembly according to the desired reference pressure.
After closing the valve, pressure is generated using the lever pump. The adjusting wheel is used for fine adjustment until the piston reaches equilibrium with the applied weights.
The generated reference pressure is then compared with the indication of the device under test and the measurement result is recorded.
After the measurement, pressure is released through the release valve. The device under test must only be removed after the system has been completely depressurized. EP-BG10 pneumatic testing devic…
