Pressure Generation up to 700 bar
The Fluke Calibration P5514B generates hydraulic pressure from:
0 to 10,000 psi
corresponding to:
0 to 700 bar / 70 MPa.
This pressure range covers a broad spectrum of industrial pressure calibration applications.
The P5514B is particularly useful for calibration laboratories that require a manual hydraulic pressure source for medium and high-pressure instruments.
Hydraulic Pressure Comparator
The P5514B is designed as a:
Hydraulic Pressure Comparator.
A pressure comparator supplies the same pressure to a reference instrument and a device under test.
A typical setup consists of:
Fluke Calibration P5514B + Reference Pressure Gauge + Device Under Test
The P5514B generates and adjusts the pressure.
The reference pressure gauge determines the actual applied pressure.
The device under test is exposed to the same pressure.
The DUT indication can then be compared directly with the reference value.
Vernier Fine Adjustment
One of the most important improvements of the Fluke Calibration P5514B is its:
Vernier fine-adjustment control.
The Vernier provides precise adjustment of hydraulic pressure and makes it easier to approach defined calibration points.
This is particularly useful for cardinal point calibration where specific nominal pressure values must be established accurately.
Once the approximate pressure has been generated, the operator can use the Vernier to make small controlled adjustments.
Precise Calibration Points
Precise pressure adjustment is particularly important when calibrating high-resolution digital pressure gauges and transmitters.
The P5514B allows the operator to approach the required calibration point and then make small corrections until the desired reference pressure is achieved.
After stabilization, the reference and DUT values can be recorded.
Screw Press
The Fluke Calibration P5514B uses a screw press for pressure generation and fine adjustment.
The specified screw press displacement is:
20 cm³.
The relatively large displacement provides sufficient volume adjustment for practical calibration applications while still allowing precise pressure control.
75 cm³ Reservoir
The hydraulic reservoir has a volume of:
75 cm³.
The reservoir supplies the hydraulic medium required for pressure generation and provides sufficient capacity for typical comparison calibration setups.
Improved Reservoir Valve Sealing
The P5514B incorporates improved:
reservoir valve sealing.
According to Fluke Calibration, this design improvement makes the P5514B a more stable pressure generator than previous versions of the model.
Improved pressure stability is particularly useful when waiting for a calibration point to stabilize before recording measurement values.
Tool-Free Test Connections
The Fluke Calibration P5514B incorporates tool-free test connectors.
This simplifies connection of the reference pressure instrument and device under test.
The connection concept is designed to provide secure, leak-free installation without requiring conventional sealing tape at the test connectors.
This reduces setup time and simplifies changes between different devices under test.
NPT and BSP Adapters
The P5514B includes adapters for common pressure connection sizes.
The standard adapter configuration includes:
- 2 × 1/4 NPT adapters
- 1 × 1/2 NPT adapter
- 1 × 1/4 BSP adapter
- 1 × 1/2 BSP adapter
This combination covers many common industrial pressure instruments.
Additional adapters can be used when other thread types or connection sizes are required.
Pressure Gauge Calibration
The Fluke Calibration P5514B is particularly suitable for pressure gauge calibration.
A reference pressure gauge is connected to one test port.
The pressure gauge under test is connected to the second test port.
The P5514B applies the same hydraulic pressure to both instruments.
The difference between the reference indication and the DUT indication can then be determined at defined calibration points.
Digital Pressure Gauge Calibration
Digital pressure gauges can be calibrated using the same comparison principle.
A high-accuracy digital reference gauge can be connected to the P5514B.
The hydraulic pressure is increased through a defined sequence of calibration points.
The Vernier fine adjustment makes it easier to approach exact nominal pressures.
After reaching the maximum pressure, the calibration can be repeated in the decreasing direction to evaluate characteristics such as hysteresis.
Pressure Transmitter Calibration
The Fluke Calibration P5514B can also be used for pressure transmitter calibration.
A typical setup consists of:
P5514B + Reference Pressure Gauge + Pressure Transmitter + Electrical Calibrator
The P5514B generates the hydraulic input pressure.
The reference gauge measures the actual pressure.
An electrical calibrator measures the transmitter output.
For many industrial transmitters, the output signal is:
4 to 20 mA.
This arrangement allows the complete relationship between input pressure and electrical output to be evaluated.
Pressure Switch Testing
The P5514B is also suitable for testing pressure switches.
Pressure can be increased slowly until the switch changes state.
The corresponding switching pressure is measured using the reference pressure gauge.
The pressure can then be reduced until the switch returns to its original state.
This allows determination of:
- Switching pressure
- Reset pressure
- Switching hysteresis
The Vernier fine adjustment is particularly useful for accurately determining these switching points.
Pressure Transducer Calibration
Pressure transducers and pressure sensors can also be tested using the Fluke Calibration P5514B.
The reference instrument and pressure transducer are exposed to the same hydraulic pressure.
The electrical output of the transducer can then be measured and compared with the reference pressure at different calibration points.
Combination with Fluke Calibration 2700G
The P5514B can be combined with:
Fluke Calibration 2700G Reference Pressure Gauges.
This transforms the hydraulic comparator into a complete manual pressure calibration system.
The P5514B generates and adjusts the pressure while the 2700G provides the reference pressure measurement.
Fluke offers several bundled configurations with different 2700G pressure ranges.
P5514B-2700G-1
The:
P5514B-2700G-1
combines the hydraulic pressure comparator with one 2700G reference pressure gauge.
This provides a compact bench-top pressure calibration solution for applications where one reference pressure range is sufficient.
P5514B-2700G-3
For broader pressure coverage, Fluke offers the:
P5514B-2700G-3.
This configuration combines the P5514B with three reference pressure gauges:
- 2700G-G70M
- 2700G-G20M
- 2700G-BG7M
Together, this system covers an overall pressure range from approximately:
-12 psi to 10,000 psi
or:
-80 kPa to 70 MPa.
Using multiple reference gauges provides optimized reference measurement across different pressure ranges.
Alternative to a Deadweight Tester
When combined with suitable 2700G reference pressure gauges, the Fluke Calibration P5514B provides an easy-to-use alternative to traditional deadweight testers for many pressure calibration applications.
A digital reference gauge eliminates the need to handle piston-cylinder assemblies and masses during routine comparison calibration.
The P5514B provides the pressure generation while the digital reference provides the calibrated pressure measurement.
This can simplify routine calibration workflows.
Pressure Generator, Not Pressure Reference
The distinction between pressure generation and reference measurement is important.
The Fluke Calibration P5514B itself does not provide the metrological reference value.
It is a:
hydraulic pressure generator and comparator.
The reference value is supplied by a connected:
- Reference pressure gauge
- Digital reference gauge
- Reference pressure transducer
- Other suitable pressure standard
The achievable calibration uncertainty therefore depends on the selected reference instrument and the complete measurement setup.
Viton® Seal Version
The standard:
P5514B-70M
uses:
Viton® seals.
This configuration covers the complete pressure range from:
0 to 10,000 psi / 700 bar / 70 MPa.
The selected hydraulic medium must always be compatible with the installed seals and the device under test.
Ethylene Propylene Seal Version
For applications requiring different fluid compatibility, Fluke also offers:
P5514B-70M-EP.
This configuration uses:
Ethylene Propylene seals.
Fluke identifies these seals for applications involving media such as solvents, fuel oils, brake fluids and similar aggressive fluids.
The compatibility of the selected pressure medium with all components of the calibration setup must be verified before use.
Bench-Top Operation
The Fluke Calibration P5514B can be mounted and operated on a calibration bench.
Its compact dimensions make it suitable for permanent installation as part of a manual pressure calibration workstation.
A reference gauge can remain installed while different devices under test are connected as required.
Mobile Applications
The P5514B is also suitable for mobile applications.
With dimensions of approximately:
280 × 280 × 254 mm
and a weight of approximately:
5 kg / 11 lb,
the comparator can be transported significantly more easily than many traditional high-pressure calibration systems.
This makes it useful for calibration and maintenance work outside a permanent laboratory.
Robust Design
The Fluke Calibration P5514B was designed for routine professional pressure calibration.
Its robust mechanical construction and improved reservoir valve sealing support reliable operation in both laboratory and mobile applications.
The simple manual operating principle also reduces dependence on electrical power or compressed-gas supplies.
No Electrical Power Required
The P5514B generates pressure mechanically.
No electrical power is required for the pressure comparator itself.
This is particularly useful for mobile calibration and service applications.
If a digital reference pressure gauge is used, only the reference instrument requires its own power supply.
