europascal EP is a powerful high-pressure gas generator designed to provide pneumatic pressures up to 1,100 bar for demanding pressure calibration systems, pressure controllers and high-pressure test applications. The system enables very high gas pressures to be generated from a comparatively low-pressure supply and is therefore particularly suitable for professional calibration laboratories requiring clean pneumatic pressure at ranges normally associated with hydraulic systems.
A proven europascal application uses the high-pressure booster to increase an input pressure of approximately 10 bar nitrogen to pressures up to 1,100 bar. The generated pressure can then supply high-pressure calibration equipment such as pressure controllers, piston gauges and complete automated calibration systems. europascal has documented this principle in its own laboratory, where the high-pressure booster supplies a Fluke 8370A pressure controller used together with a Fluke PG7202-AMH piston gauge.
This makes the europascal EP particularly useful where extremely high pneumatic pressure is required but hydraulic pressure generation is undesirable. Using gas instead of oil avoids contamination of pressure instruments with hydraulic fluid and allows pneumatic calibration of compatible pressure gauges, sensors, transmitters and reference standards.
At europascal, high-pressure technology forms part of a pressure calibration portfolio extending from very low pressures to 10,000 bar. The company’s accredited pressure laboratory covers measurement ranges from 1 Pa to 10,000 bar.

Pneumatic Pressure up to 1,100 bar
The defining feature of the europascal EP is its ability to generate gas pressure up to:
1,100 bar
or approximately:
110 MPa / 15,950 psi.
This is an exceptionally high pressure for pneumatic calibration.
Conventional pneumatic calibration systems frequently operate at considerably lower pressures. Applications at several hundred bar and above often use hydraulic pressure generation because liquids are significantly less compressible than gases.
The europascal EP provides an alternative for applications where high pressure and a gaseous pressure medium are required.
From 10 bar Nitrogen to 1,100 bar
The operating principle is based on pressure intensification.
In a documented europascal laboratory application, the high-pressure booster increases approximately:
10 bar nitrogen
to as much as:
1,100 bar.
This means the laboratory does not require a conventional 1,100 bar gas supply.
Instead, the booster generates the required high pressure from a much lower-pressure nitrogen source.
This concept is particularly useful for permanent high-pressure calibration installations.
High-Pressure Gas Booster Principle
The europascal EP works as a high-pressure gas booster rather than a conventional manual pressure comparator.
The booster receives gas at the inlet and compresses it to a significantly higher outlet pressure.
The resulting high-pressure gas can then be supplied to downstream calibration equipment.
A typical system can consist of:
Nitrogen supply → europascal EP high-pressure booster → pressure controller → reference standard / device under test
This arrangement separates pressure generation from precision pressure regulation and measurement.
The EP provides the required high-pressure supply, while a pressure controller can regulate the final calibration pressure.
Ideal Supply for High-Pressure Controllers
A high-pressure controller can only generate or regulate pressure within its range if a suitable pressure supply is available.
This is where the europascal EP becomes particularly valuable.
The booster provides the high supply pressure required by the controller.
europascal has publicly documented a system in which its high-pressure booster supplies a Fluke 8370A pressure controller, which is operated together with a Fluke PG7202-AMH piston gauge.
This demonstrates the suitability of the booster for advanced automated pressure calibration systems.
Automated Pressure Calibration
The europascal EP can form the pressure generation stage of an automated calibration workstation.
A typical configuration may include:
- Nitrogen supply
- europascal EP high-pressure gas generator
- High-pressure controller
- Reference pressure instrument
- Device under test
- Calibration software
- Safety and pressure connection equipment
The booster provides the high-pressure supply.
The controller then automatically adjusts the required calibration pressure.
The reference standard determines the pressure value, while calibration software can control the procedure and record measurement results.
This architecture is particularly useful for laboratories with recurring high-pressure calibration workloads.
Pneumatic Calibration without Hydraulic Oil
One of the major advantages of the europascal EP is pneumatic operation.
Many conventional high-pressure generators use hydraulic oil.
Although hydraulic systems are highly effective for pressure generation, they introduce liquid into the pressure circuit.
This can be undesirable for devices that are designed for gas service.
Using nitrogen or another approved gas eliminates hydraulic oil from the calibration circuit.
This can reduce contamination risks and simplify calibration of instruments intended exclusively for pneumatic applications.
Nitrogen as Pressure Medium
Nitrogen is particularly suitable for many pressure calibration applications because it is dry and inert under normal calibration conditions.
europascal’s documented high-pressure application specifically uses nitrogen as the medium supplied to the high-pressure booster.
A dry gas supply also helps protect sensitive pressure instruments against moisture contamination.
The suitability of the pressure medium for the connected equipment must always be verified before operation.
Suitable for Reference Pressure Systems
The europascal EP can provide the pressure supply for high-performance reference systems.
For example, europascal operates a Fluke PG7202-AMH piston gauge for automated pneumatic calibrations up to 1,000 bar and supplies the associated system through a high-pressure booster capable of reaching 1,100 bar.
The additional pressure capability above the calibration range provides the supply pressure required by the pressure regulation system.
This is an important distinction:
The EP is primarily the pressure source.
The connected pressure controller is responsible for precise pressure regulation.
The reference pressure instrument establishes the metrological reference.
Calibration of High-Pressure Instruments
When integrated into an appropriate calibration system, the europascal EP can support calibration of high-pressure instruments such as:
- Digital pressure gauges
- Reference pressure gauges
- Pressure sensors
- Pressure transmitters
- Pressure transducers
- High-pressure controllers
- Pressure modules
- Industrial pressure instrumentation
The exact usable calibration range depends not only on the booster but also on the pressure ratings and measurement ranges of all other components in the system.
Pressure Sensors and Transducers
High-pressure sensors are used in numerous industrial and research applications.
A calibration workstation supplied by the europascal EP can generate the required pneumatic pressure while a reference instrument measures the actual pressure.
The electrical output of the sensor can simultaneously be measured using a precision multimeter or process calibrator.
Typical outputs include:
- mV/V
- Voltage
- 4–20 mA
- Digital signals
This allows the relationship between pressure and electrical output to be evaluated across the required calibration range.
Pressure Transmitter Calibration
The same principle applies to pressure transmitters.
The EP supplies the high-pressure system while a pressure controller generates the individual calibration points.
A reference pressure instrument provides the traceable pressure value.
The transmitter output can then be compared with the corresponding reference pressure.
This creates a complete pressure-to-electrical calibration system.
Pressure Gauge Calibration
High-pressure digital and analog pressure gauges can also be calibrated using a system supplied by the europascal EP.
The booster generates the necessary supply pressure, while a pressure controller or suitable regulation system approaches the individual calibration points.
The readings of the device under test are compared with a calibrated reference pressure instrument.
Measurements can be performed with increasing and decreasing pressure to evaluate the behavior of the instrument throughout its measuring range.
Pressure Generation and Pressure Measurement
It is important to distinguish between pressure generation and pressure measurement.
The europascal EP generates the high-pressure gas required by the calibration system.
It does not replace the metrological reference.
A complete calibration workstation therefore requires a suitable calibrated pressure reference.
Depending on the required measurement uncertainty, this may be:
- A reference pressure gauge
- A high-accuracy pressure transducer
- A piston gauge
- Another suitable reference standard
This modular principle allows the pressure generation and reference measurement components to be optimized independently.
Integration with Pressure Controllers
Combining the europascal EP with an automated pressure controller provides significant advantages.
The booster generates the high supply pressure.
The pressure controller then regulates this supply to the exact setpoint required for calibration.
This provides:
- Automatic pressure generation
- Controlled pressure adjustment
- Repeatable calibration points
- Reduced manual intervention
- Improved calibration throughput
- Easier integration with calibration software
For laboratories performing a large number of calibrations, automation can significantly improve efficiency.
High-Pressure Calibration Expertise
The europascal EP benefits from europascal’s extensive experience in pressure metrology.
europascal operates an accredited pressure calibration laboratory covering ranges from:
1 Pa to 10,000 bar.
This exceptionally broad pressure range provides practical experience with pressure generation, regulation, measurement and calibration across pneumatic and hydraulic applications.
The same expertise supports the design and integration of customized high-pressure calibration systems.
Customized Pressure Calibration Systems
High-pressure gas calibration frequently requires more than a single instrument.
Depending on the application, a complete system may require:
- High-pressure gas booster
- Pressure controller
- Reference standard
- Safety valves
- Shut-off valves
- Pressure reducers
- High-pressure tubing
- Suitable fittings
- Pressure adapters
- Device-under-test connections
- Calibration software
europascal provides customized calibration solutions designed for individual laboratory and industrial requirements. Its current product portfolio emphasizes tailored calibration systems and support across pressure ranges from vacuum to 10,000 bar.
Typical System Configuration
A professional high-pressure calibration system can be configured as follows:
1. Nitrogen supply
Provides the initial gas pressure.
2. europascal EP
Boosts the gas pressure up to 1,100 bar.
3. Pressure controller
Regulates the boosted pressure to the required calibration setpoint.
4. Reference pressure instrument
Provides the traceable reference value.
5. Device under test
Receives the controlled pressure.
6. Calibration software
Controls and documents the calibration procedure where automation is required.
This modular architecture allows individual components to be selected according to the required pressure range and measurement uncertainty.
High-Pressure Safety
Pneumatic pressure up to 1,100 bar stores a substantial amount of energy.
High-pressure gas systems therefore require appropriate safety precautions.
All components must be specifically rated for the maximum operating pressure.
This applies to:
- Tubing
- Fittings
- Valves
- Adapters
- Pressure controllers
- Reference instruments
- Devices under test
- Safety equipment
The maximum permissible pressure of the weakest component determines the permissible operating pressure of the complete system.
High-pressure gas equipment should only be operated by appropriately trained personnel and in accordance with the applicable operating and safety instructions.

The europascal EP is particularly suitable for:
- High-pressure pneumatic calibration

europascal EP Compared with Hydraulic Pressure Generators
The main distinction between the europascal EP and a hydraulic high-pressure generator is the pressure medium.
A hydraulic pressure generator uses oil or another liquid.
The europascal EP generates:
high-pressure gas.
This difference is particularly important when the devices being calibrated must remain free from oil.
Hydraulic systems generally offer straightforward generation of extremely high pressures because liquids have low compressibility.
Generating comparable pressures pneumatically is considerably more demanding.
The ability of the europascal EP to provide gas pressure up to 1,100 bar therefore makes it a specialized solution for high-pressure pneumatic calibration.
Why Choose the europascal EP?
The europascal EP provides an effective solution when very high pneumatic pressure is required for professional calibration.
A documented europascal application demonstrates the core capability clearly: approximately 10 bar nitrogen is boosted to as much as 1,100 bar, providing the high-pressure supply for a Fluke 8370A pressure controller and a calibration system incorporating a Fluke PG7202-AMH piston gauge.
This enables pneumatic calibration at pressures that would otherwise often require hydraulic pressure generation.
The separation between pressure generation, pressure regulation and reference measurement also provides a flexible system architecture. The EP supplies the pressure, a controller can regulate the required setpoints and an appropriate reference standard establishes metrological traceability.
For calibration laboratories, this enables customized high-pressure systems to be designed around the required range, measurement uncertainty and level of automation.
At europascal, we combine high-pressure equipment with extensive practical experience in pressure metrology. Our accredited pressure laboratory covers measurement ranges from 1 Pa to 10,000 bar, supporting pressure calibration solutions across an exceptionally wide range.
