P5514B Hydraulic Pressure Comparator
The P5514B Hydraulic Pressure Comparator is a simple, robust and economical pressure test pump for calibrating gauges, switches and transducers with accurate, fine adjust capabilities. It generates pressure to 10 000 psi (70 MPa), with a new Vernier 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.
The test ports have been improved with a rotating collar design that make it a snap to connect devices under test (DUTs). Test port connections include adapters for common sizes of NPT and BSP. Connections are tool free, another improvement over the previous model.

About pressure comparators
A pressure comparator or hydraulic test pump 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 costeffective 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 Pressure Comparator, 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.
