The P5514B Hydraulic Comparison Test Pump is a simple, robust and economical pressure comparator 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.
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.
