Pressure CalibratorsFLUKE Calibration P5514B Hydraulic Pressure Comparator
The P5514B Hydraulic Pressure Comparator is a simple, robust and economical pressure comparison test pump for calibrating gauges, switches and transducers with precise, fine adjust capabilities. It generates pressure to 10 000 psi (70 MPa), with a new Vernier fine-adjustment control that enables cardinal point calibrations. The P5514B can be mounted easily on a bench or used in mobile applications. Its robust design, with improved reservoir valve sealing, makes it a more stable pressure generator than previous versions of this model. Test port connections include adapters for common sizes of NPT and BSP. Connections are tool free, no sealing tape required, another design improvement which, coupled with the new Vernier fine adjustment control, simplifies and improves pressure testing.
About pressure comparison test pumps
A pressure comparison test pump or pressure comparator supplies the same precisely controlled pressure to both a reference gauge and device under test for calibration. Fluke Calibration hydraulic test pumps are used for checking pressure measuring instruments against master test gauges, indicators or transducers. These cost-effective instruments, which include several features from our popular line of hydraulic deadweight testers, are capable of easily generating high pressures and often include a Vernier for precise control for important calibration requirements.
Make it a pressure calibrator
The Fluke Calibration P5514B Hydraulic Comparison Test Pump, when combined with the 2700G Reference Pressure Gauges, becomes an easy-to-use alternative to traditional deadweight testers that covers a wide range of workload. For convenience, the P5514B is bundled together with selected 2700G Reference Pressure Gauges for a complete bench top pressure calibration solution. These pressure calibrators provide the accuracy, reliability, and capability you need to calibrate dial gauges, digital test gauges and pressure transmitters.
For example, the P5514B-2700G-3 is a P5514B comparison test pump, bundled together with 2700G-G70M, 2700G-G20M, 2700G-BG7M. This calibrator has three pressure ranges corresponding to the three 2700G Reference Pressure Gauges in the bundle and covers a total pressure range of –12 psi to 10 000 psi (–80 kPa to 70 MPa).

Pressure CalibratorsFLUKE Calibration P3100 Hydraulic Deadweight Testers
The P3100 models are available in single or dual piston format. Unit can be supplied in psi, bar, kgf/cm², and MPa. This robust instrument is highly accurate, quick and easy to use. Units feature a built-in priming pump for large volume applications, piston flotation indicators and a high quality screw press for fine pressure control.
Operating principle
Deadweight testers are the high performance pressure standards for pressure measurement. Utilizing the well proven piston-gauge system consisting of a vertically mounted, precision lapped piston and cylinder assembly, accurately calibrated weight masses (Force) are loaded on the piston (Area), which rises freely within its cylinder. These weights balance the upward force created by the pressure within the system. The pressure is measured when placed on a correctly spinning and floating piston. The total pressure measured is the summation of the weights plus the piston weight carrier assembly.Instrument base
There are three basic variations in the hydraulic offering; single low pressure, single high pressure and dual piston models. Pressure is generated and controlled by means of a high quality screw press located on the front of the tester. A built-in hand pump is included as standard for all hydraulic models to prime the system and accommodate large volume requirements.
Piston/cylinder assemblies
The piston/cylinder assembly is the heart of each deadweight tester. They are manufactured from materials that provide stability, durability, and low thermal coefficients and distortion. Our experience and knowledge of piston/cylinder production and calibration ensure the precision and performance required for today’s demanding calibration requirements.
Weight masses
Standard weight masses are series 3 nonmagnetic austenitic stainless steel. Each mass is marked with the serial number of the instrument and the nominal pressure value relative to the high or low-pressure piston, when applicable. Optional fractional weights are stainless steel and/or solution heat treated aluminum.
Gravity correction
Gravity varies significantly with geographical location and this variation has a direct effect on the force of the weights and the accuracy of the deadweight tester. Each instrument can be calibrated to local gravity at no extra cost. If unspecified, instruments will be calibrated to Standard Gravity at 980.665 cm/s2.(0 reviews) -
Pressure CalibratorsFLUKE 750P Series Pressure Modules
Fluke 750P Series Pressure Modules will turn your Fluke multifunction calibrator into a full-fledged pressure calibrator. These flexible modules not only work with multifunction calibrators like the 725, 726 or 750 Series Calibrators but also extend the measurement range of Fluke pressure calibrators. Since the pressure modules are calibrated independently, they can be swapped from one calibrator to another without a loss of accuracy or traceability.
Measuring pressure with Fluke 750P Series Pressure modules is as easy as connecting the module to a pressure source or hand pump, connecting the pressure module cable to the calibrator and then applying pressure from the pressure source. At the touch of a button the measured pressure is displayed digitally on the calibrator in up to 11 different engineering units quickly giving you the data you need. And, with “no tools required” connectors you don’t even need to reach for a wrench to make connections.
When used with the 750 Series Documenting Process Calibrators pressure readings can even be date/time stamped and stored in documented calibration records for later retrieval. This saves time, eliminates errors, and supports compliance with quality standards and regulations.
A complete family of pressure modules
With over 50 pressure modules covering pressure calibration and measurement workloads from 1 inH20 to 10,000 psi (2.5 mBar to 690 bar) finding a model to meet the needs of your specific application is easier than ever. All modules include NPT, metric (BSP) and M20 adapters.

Designed to go where you work
Pressure instruments are often installed in harsh, hard to reach locations, so you need test tools that handle rough service. 750P Series Pressure Modules feature a rugged protective boot that guards the module against shock and seals against dirt and dust, if you accidently drop them, there’s no need to worry. The 750P series modules are also specified across a broad temperature range. Though more accurate across a narrower temperature range if used indoors, these modules are designed and specified to deliver traceable pressure measurements in environments from -10 °C to +50 °C.
