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 E-DWT Electronic Deadweight Tester
A modern alternative to the traditional deadweight tester
E-DWT-H breaks new ground, improving the hydraulic pressure calibration process. E-DWT-H is an electronic calibrator designed to replace mechanical, piston-cylinder and weight based deadweight testers. It’s a lighter, easier-to-use deadweight tester alternative that is at home in the lab or instrument shop, as well as in the field performing in-situ calibrations and tests. This complete hydraulic pressure calibration system combines the convenience and precision of continuous, realtime electronic pressure measurement with the simple and direct operation of high quality operator controlled pressure generation hardware. E-DWT-H one year measurement uncertainty is ±0.02% of reading with ranges up to 30,000 psi. It can be configured to provide this uncertainty from its full scale down to 1% of its range. Built-in pressure generation and control hardware allow the operator to fill and prime the system under test and generate and precisely adjust pressure throughout the range with ease.
Broad workload coverage
The E-DWT-H has the operational versatility to calibrate and test a broad range of pressure measuring instruments including:
- Analog gauges
- Transducers
- Calibrators
- Sensors
- Transmitters
AutoTest™ lets E-DWT operators quickly define test points and adjust all of the range-dependent settings with a single function.
The resolution and stability test used by the RPM4-E-DWT are set according to the range of the device under test. The upper limit setting is also set and provides range-based warnings and overpressure protection. While running AutoTests, the operator is prompted to set each sequential test point and test data is stored in the RPM4-E-DWT for recall or download. Typical test setup is quick and easy, but more complex tests can also be stored and reused.
Deadweight tester performance with digital measurement convenience
E-DWT-H offers precision, low measurement uncertainty and the stability over time of a conventional deadweight tester without the inconveniences associated with the piston-cylinders, weights, hand pumps, and interconnecting plumbing.
- No weights to load and unload or regularly send out for calibration
- No need to know and correct for local gravity or ambient temperature
- No piston-cylinder changes; switch Q-RPT ranges in seconds
- Not sensitive to level or vibration
- Able to set and read any pressure value exactly, no minimum increment limited by smallest available masses
- Operates in any unit of measure while deadweight tester is typically limited to the pressure unit stamped on the mass
- Perfect for applications that require setting a nominal pressure precisely on the device under test and measuring it, such as analog gauge calibration
- On-board, AutoTest calibration routines and data acquisition
- Interfaceable with a PC or laptop to allow for automated data acquisition
- Two year calibration interval supported at measurement uncertainty of ±0.025% of reading.
- Easily recalibrated without crossfloating. Automated calibration of E-DWT-H is possible using COMPASS® for Pressure software.
Versatility to cover a broad workload in a variety of environments
The E-DWT-H is at home in metrology and calibration labs, on the production floor or in the field. It operates with Sebacate calibration fluid, mineral oil, Skydrol® and other liquids. An optional battery/charger pack supports up to eight hours of operation away from line power.
