The Fluke Calibration PG7601 Gas Piston Gauge is a high performance pressure standard designed for demanding pneumatic pressure calibration and pressure metrology applications. As part of the Fluke Calibration PG7000 family, the PG7601 combines precision piston cylinder technology, carefully characterized masses and sophisticated system functionality to provide highly accurate and stable pressure references.

The PG7601 is designed for calibration and reference laboratories where low measurement uncertainty, excellent long term stability and reliable metrological traceability are essential. Its operating principle is based on the fundamental relationship between force and area. Precisely characterized masses apply a known force to a piston cylinder assembly with a known effective area, generating a reference pressure that can be calculated with very high accuracy.

This makes the Fluke Calibration PG7601 an excellent solution for calibrating precision pressure controllers, digital pressure gauges, pressure transducers and other high accuracy pressure standards.

At europascal, customers benefit from extensive expertise in pressure calibration, piston gauges, pressure controllers and professional calibration technology.

Professional metrology applications

The PG7601 is suitable for accredited calibration laboratories, reference laboratories, research facilities and industrial metrology departments.

High Accuracy Gas Pressure Calibration

The Fluke Calibration PG7601 Gas Piston Gauge realizes pressure using the established piston gauge principle.

The fundamental relationship is:

p = F / A

where p is pressure, F is the force acting on the piston and A is the effective area of the piston cylinder assembly.

For high accuracy pressure calibration, the practical pressure calculation also considers additional influence quantities.

These may include:

Local gravitational acceleration

Air buoyancy of the masses

Piston cylinder temperature

Thermal expansion

Pressure deformation of the piston cylinder assembly

Mass calibration values

Pressure medium characteristics

Reference level differences

Environmental conditions

Considering these quantities enables the generated pressure to be determined with very low uncertainty.

This fundamental measurement principle is one of the main reasons why piston gauges are widely used as reference standards in professional pressure metrology.

Precision Piston Cylinder Technology

The piston cylinder assembly is the central metrological component of the Fluke Calibration PG7601.

During operation, gas pressure acts on the piston and balances the force produced by the applied mass load. When the correct pressure is reached, the piston operates at its specified float position.

The effective area of the piston cylinder assembly is precisely characterized through calibration.

Together with the calibrated mass values, this effective area forms the basis for determining the generated pressure.

Correct piston rotation, stable float position and appropriate operating conditions are important for obtaining optimum measurement results.

The precision construction of the piston cylinder assembly provides the stability and reproducibility required for high level pressure calibration.

Traceable Pressure Realization

Metrological traceability is a fundamental requirement for professional calibration laboratories.

The Fluke Calibration PG7601 provides a clearly defined measurement chain based on physical quantities that can be linked to recognized measurement standards.

The masses used to load the piston are individually characterized and calibrated. Their values are combined with the local gravitational acceleration to determine the force acting on the piston.

The effective area of the piston cylinder assembly is also characterized through calibration against suitable higher level pressure standards.

Temperature measurements and other environmental corrections are incorporated into the pressure calculation where required.

This approach enables laboratories to maintain a documented and technically transparent traceability chain for pneumatic pressure calibration.

Efficient Calibration Workflows

High accuracy pressure calibration requires not only excellent measurement performance but also consistent laboratory procedures.

The PG7601 can be used to generate stable reference pressures at defined calibration points.

A typical calibration sequence includes increasing and decreasing pressure points across the operating range of the device under test.

The values indicated by the device under test are compared with the pressure generated by the piston gauge.

This allows important metrological characteristics to be evaluated, including:

Measurement deviation

Repeatability

Hysteresis

Linearity

Zero behavior

Resolution

Long term stability

The results can then be incorporated into the measurement uncertainty evaluation and calibration certificate.

Advanced System Configuration and Automation

The PG7000 platform is designed to support sophisticated pressure calibration systems.

Depending on the laboratory configuration, the Fluke Calibration PG7601 can be combined with compatible pressure generation, measurement and automation components.

Automation can significantly improve efficiency when a laboratory performs repetitive high accuracy calibrations.

Automated functions can help reduce manual intervention, improve consistency between calibration sequences and minimize operator influence.

This makes the PG7601 suitable not only for specialized reference measurements but also for laboratories requiring efficient routine calibration with demanding uncertainty requirements.

Technical Specifications of the Fluke Calibration PG7601

The exact performance of the PG7601 depends on the piston cylinder assembly, mass set, pressure range and selected system configuration.

The actual pressure range and achievable measurement uncertainty depend on the selected piston cylinder module, mass set and operating conditions. The specifications for the complete configuration should therefore be evaluated when selecting a PG7601 system.

Ideal for Demanding Pressure Calibration Applications

The Fluke Calibration PG7601 is particularly suitable for applications where pressure measurement performance and long term stability are critical.

Calibration Laboratories

Accredited and industrial calibration laboratories can use the PG7601 as a high level reference standard for pneumatic pressure calibration.

Pressure Controller Calibration

High accuracy pressure controllers can be compared directly against pressures generated by the PG7601.

This enables systematic deviations, repeatability and other performance characteristics to be determined.

Digital Pressure Gauge Calibration

Precision digital pressure gauges can be calibrated at multiple increasing and decreasing pressure points.

Pressure Transducer Calibration

Pressure transducers can be evaluated by comparing their electrical output with the reference pressure generated by the piston gauge.

Piston Gauge Comparisons

The PG7601 can be used in comparison measurements with other piston gauges and pressure balances.

These comparisons are particularly useful for characterizing or verifying piston cylinder effective areas.

Reference and Metrology Laboratories

The combination of excellent stability and low measurement uncertainty makes the PG7601 suitable for laboratories maintaining high level pressure standards.
