Fluke P5513 is a precise pneumatic comparison test pump designed for professional calibration of pressure gauges, digital pressure indicators, transmitters and other pressure measuring instruments. With a pressure range from 0 to 3,000 psi / 210 bar / 20 MPa, the P5513 provides a clean and convenient solution for high-pressure pneumatic comparison calibration.
The Fluke P5513 is designed to test pressure measuring instruments against a suitable master reference instrument. Unlike a hydraulic comparator, the P5513 operates with gas and therefore eliminates the risk of contaminating the device under test with hydraulic oil or other liquid pressure media.
A high-quality screw press provides precise fine adjustment of pressure at the required calibration point. Precision needle valves allow controlled regulation of the external pressure supply and make it easier to approach specific test pressures accurately.
The P5513 requires an external pressure source, such as a suitable compressed nitrogen supply. This external supply provides the pressure required by the comparator, while the integrated controls allow the operator to regulate and finely adjust the pressure applied to the reference instrument and device under test.
Tool-free test port adapters simplify the connection of pressure instruments. Adapter sets are available for common NPT or BSP threads and require neither PTFE sealing tape nor wrenches during normal installation.
At europascal, the Fluke P5513 can be combined with suitable reference pressure gauges, adapters and calibration equipment to create a complete pneumatic pressure calibration system. For professional calibration and metrological traceability, visit the europascal Calibration Service.

Pressure Range up to 210 bar
The Fluke P5513 provides a pneumatic pressure range from:
0 to 3,000 psi
or approximately:
0 to 210 bar / 20 MPa.
This allows pneumatic comparison calibration at pressures considerably above the capabilities of many conventional hand-operated pneumatic calibration pumps.
The P5513 is therefore particularly suitable when high pneumatic pressures are required but the use of hydraulic oil or another liquid medium is undesirable.
Pneumatic Pressure Calibration
One of the main advantages of the Fluke P5513 is its pneumatic operating principle.
Pressure is applied using gas rather than hydraulic liquid.
This can be particularly important when calibrating devices that must remain free of:
- Hydraulic oil
- Water
- Other liquid contaminants
Gas pressure comparators are therefore often preferred for pressure instruments used in processes where liquid contamination cannot be tolerated.
External Pressure Source Required
The Fluke P5513 requires an external pressure source.
For example, a suitable:
nitrogen cylinder
can be used as the pressure supply.
This is an important difference compared with pneumatic hand pumps that generate pressure directly from ambient air.
The external gas supply provides the pressure energy, while the P5513 allows the operator to regulate and finely adjust the pressure applied to the calibration system.
Gas Supply Connection
The gas supply connection of the Fluke P5513 is:
1/4 NPT female.
The external pressure supply must be appropriate for the required pressure range and used in accordance with the applicable safety requirements.
All tubing, fittings, valves and other components connected to the system must be suitable for the maximum applied pressure.
Screw Press for Fine Adjustment
The Fluke P5513 incorporates a:
screw press for fine pressure adjustment.
Once the external pressure supply has brought the system close to the required calibration point, the screw press can be used to make small and controlled pressure adjustments.
This is particularly useful when calibrating high-resolution digital pressure gauges or transmitters.
Precise Calibration Points
Accurately approaching defined calibration points is an important part of professional pressure calibration.
The P5513 provides the fine adjustment required to establish these pressure points precisely.
A typical calibration sequence can include increasing pressure through several points across the DUT range and subsequently reducing pressure through the same points.
This allows both indication error and pressure-dependent behavior of the device under test to be evaluated.
High-Quality Needle Valves
The Fluke P5513 incorporates high-quality needle valves for precise pressure control.
The valves allow the external gas pressure supply to be carefully regulated.
This makes it possible to increase or reduce pressure in a controlled manner before performing the final fine adjustment with the screw press.
Comparison Calibration
The P5513 is designed for:
pneumatic comparison calibration.
A typical system consists of:
Pressure Supply + Fluke P5513 + Reference Pressure Instrument + Device Under Test
The external source supplies the gas pressure.
The P5513 regulates and finely adjusts the pressure.
The reference instrument measures the actual pressure.
The device under test is exposed to the same pressure.
The DUT indication can then be compared directly with the reference value.
Reference Instrument Required
The Fluke P5513 generates and regulates pressure but does not independently determine the reference pressure.
A calibrated reference pressure instrument is therefore required.
Suitable references can include:
- Digital reference pressure gauges
- Reference pressure monitors
- Pressure transfer standards
- Other suitable calibrated pressure references
The accuracy and measurement uncertainty of the complete calibration system depend primarily on the selected reference instrument and the calibration method.
Pressure Gauge Calibration
The Fluke P5513 is particularly suitable for calibration of pressure gauges.
A reference pressure gauge is connected to one test port.
The pressure gauge under test is connected to the second test port.
Both instruments are exposed to the same pneumatic pressure.
The external pressure supply and P5513 controls are used to establish the required calibration points.
The difference between the reference pressure and DUT indication can then be determined.
Digital Pressure Gauge Calibration
Digital pressure gauges can be calibrated using the same comparison method.
A high-accuracy digital reference pressure gauge provides the reference value.
The P5513 regulates the applied pneumatic pressure.
The screw press allows precise fine adjustment when approaching the desired calibration point.
This combination provides a convenient manual system for high-pressure pneumatic calibration.
Pressure Transmitter Calibration
The Fluke P5513 can also be used for pressure transmitter calibration.
A typical setup consists of:
P5513 + Reference Pressure Instrument + Pressure Transmitter + Electrical Calibrator
The P5513 controls the pneumatic input pressure.
The reference pressure instrument measures the actual applied pressure.
An electrical calibrator measures the transmitter output.
For many industrial pressure transmitters, this output is:
4 to 20 mA.
This arrangement allows the complete pressure-to-current characteristic of the transmitter to be evaluated.
Pressure Transducer Calibration
Pressure sensors and transducers can also be tested with the P5513.
The reference instrument and pressure transducer are exposed to the same gas pressure.
The transducer’s electrical output can then be measured at defined pressure points and compared with the reference pressure.
Clean Calibration Medium
Cleanliness is one of the most important reasons for choosing a pneumatic comparator instead of a hydraulic system.
The Fluke P5513 avoids introducing hydraulic fluid into the connected instrument.
This can be advantageous for:
- Pneumatic pressure gauges
- Gas pressure transmitters
- Pressure sensors
- Clean process instrumentation
- Devices sensitive to liquid contamination
The gas used must always be suitable for the P5513 and the device under test.
Tool-Free Test Connections
The Fluke P5513 features test port adapters designed for convenient instrument installation.
According to Fluke, these adapters require:
no PTFE tape
and:
no wrenches.
This makes changing between reference instruments and devices under test significantly easier.
For calibration laboratories with a high throughput of different instruments, this can reduce setup time.
NPT and BSP Adapter Sets
The Fluke P5513 is available with two sets of test port adapters.
The supported sizes include:
- 1/8 inch
- 1/4 inch
- 3/8 inch
- 1/2 inch
Configurations are available with:
NPT
or:
BSP
connections.
This provides compatibility with many commonly used pressure instruments.
Combination with Fluke Calibration 2700G
The P5513 can be combined with Fluke Calibration 2700G Reference Pressure Gauges.
The P5513 provides pneumatic pressure regulation and fine adjustment, while the 2700G provides the calibrated reference pressure measurement.
This combination creates a complete manual pneumatic pressure calibration solution.
P5513-2700G-1
Fluke offers the:
P5513-2700G-1.
This configuration combines the P5513 pneumatic comparator with one:
2700G-G20M Reference Pressure Gauge.
The system covers pressures up to:
20 MPa / 3,000 psi.
This provides a compact solution when one reference gauge is sufficient for the required calibration workload.
P5513-2700G-3
For applications requiring optimized reference coverage across several pressure ranges, Fluke also offers:
P5513-2700G-3.
This configuration combines the P5513 with three reference pressure gauges:
- 2700G-G20M
- 2700G-BG7M
- 2700G-BG700K
Using several reference ranges allows the most appropriate reference gauge to be selected according to the range of the device under test.
Accredited Calibration Configurations
Fluke also lists P5513 and 2700G configurations supplied with accredited calibration.
These include:
P5513-2700G-1/C
and:
P5513-2700G-3/C.
These configurations can be useful when a complete system with documented calibration traceability is required.
The exact calibration scope and measurement uncertainty should always be checked for the selected reference gauge configuration.
Bench Calibration
The Fluke P5513 is well suited to bench pressure calibration.
A reference pressure instrument and DUT can remain clearly visible while the operator adjusts the applied pressure using the needle valves and fine adjustment screw press.
This provides a straightforward workflow for calibration, adjustment and testing.
Robust Carrying Case
The P5513 is supplied in a:
sturdy carrying case with lid.
This protects the comparator during storage and transportation.
The enclosure also makes the instrument suitable for calibration applications where equipment must be transported between different work locations.

The dimensions of the Fluke P5513 are approximately:
440 × 300 × 215 mm
or:
17.5 × 12 × 8.5 inches.
The compact footprint allows the comparator to be integrated into a calibration bench without requiring a large amount of workspace.
Weight
The P5513 weighs approximately:
8 kg / 17 lb.
This allows the unit to be transported when required while still providing the robust construction necessary for high-pressure pneumatic operation.

P5513 vs. P5510
The Fluke P5513 and P5510 are both pneumatic comparison test pumps, but they are designed for different pressure ranges.
The P5510 provides pressure generation up to approximately:
300 psi / 20 bar.
It also incorporates its own pressure and vacuum generation capability.
The P5513 extends the pneumatic pressure range to:
3,000 psi / 210 bar.
However, the P5513 requires an external high-pressure gas source.
The P5513 is therefore the more appropriate choice when substantially higher pneumatic pressures are required.
P5513 vs. P5514B
The Fluke P5513 should also be distinguished from the hydraulic P5514B.
The P5513 uses:
gas pressure
and operates up to:
3,000 psi / 210 bar.
The P5514B uses:
hydraulic pressure
and extends the pressure range up to:
10,000 psi / 700 bar.
The P5513 is particularly advantageous when the device under test should remain free from liquid contamination.
The P5514B is better suited when substantially higher pressures are required and hydraulic media are acceptable.
P5513 vs. P5515
For very high hydraulic pressures, Fluke Calibration also offers the P5515.
The P5513 covers pneumatic pressure up to:
3,000 psi / 210 bar.
The P5515 provides hydraulic pressure generation up to:
20,000 psi / 1,400 bar.
The appropriate comparator therefore depends on both the required pressure range and the pressure medium compatible with the device under test.
