Fluke P3860-XXX High-Pressure Oil Hydraulic Deadweight Tester

The Fluke P3860-XXX High-Pressure Oil Hydraulic Deadweight Tester is able to calibrate high-pressure sensing instruments via the creation of hydraulic pressure and the addition of accurately calibrated weight masses. It is particularly well suited to calibrating transducers, transmitters, gauges, pressure switches and other pressure calibrators.

This instrument is available in three models with varying pressure ranges and measurement units. Please see the table below for details regarding the differences between these models.

Each of these models can be purchased with EITHER a 0.02% accuracy OR 0.015% accuracy. As standard they are calibrated to standard gravity (980.665cm/s²); however, it is possible to both calibrate the deadweight tester and trim the supplied weight masses in accordance with the user’s local gravity. These changes account for the localised gravitational pull on the weight masses, thereby improving the accuracy of the instrument and calibration method. PLEASE NOTE that unless specified the deadweight tester and weight masses will be calibrated/ trimmed with regard to standard gravity, as indicated above.

The weight masses supplied with the Fluke P3860-XXX High-Pressure Oil Hydraulic Deadweight Tester are marked with the instrument’s serial number and the nominal pressure values relative to the high-pressure piston. Moreover, they are constructed from series 3, non-magnetic stainless steel, ensuring that they are not affected by the earth’s magnetic field, again working to ensure the precision of this method.

Weight masses are added to the piston and cylinder assembly in order to balance the upward force created by the generation of hydraulic pressure. Dicotyl Sebacate (DOS) is the medium with which hydraulic pressure is created. When calibrating instruments with large volumes, the oil reservoir can be re-filled in order to generate the required pressures. A high-quality integrated hand-pump is connected to a seven-to-one intensifier, which facilitates the quick creation of hydraulic pressure in the system.

To determine the final pressure value, when the piston is at the ‘mid-floatation’ position, as indicated by the floatation indicator, the nominal values on the weight masses (added to the piston) are combined with the weight of the piston and cylinder assembly.

The piston and cylinder assembly is constructed from tungsten carbide. The assembly, like the weight masses, adds to the precision of this instrument and method; it provides longevity, stability and durability, as well as low coefficients for temperature and pressure. Further to this, the Fluke P3860-XXX High-Pressure Oil Hydraulic Deadweight Tester is supplied with an ISO/ IEC 17025 accredited calibration certificate.

As well as being accurate and simple-to-use, the Fluke P3860-XXX High-Pressure Oil Hydraulic Deadweight Tester is also easy to assemble. Its test-station design allows instruments-under-investigation to be connected quickly, whilst its adjustable feet and level vial ensures that it be set up accurately in a variety of worksites.

The Fluke P3860-XXX High-Pressure Oil Hydraulic Deadweight Tester is a versatile high-pressure calibrator optimised for reliability, accuracy, longevity and efficiency.
