The Fluke Calibration P3860BAR High Pressure Hydraulic Deadweight Tester, 40 to 4000 bar is the culmination of over 50 years experience in the design and manufacture of primary pressure standards. With features and options designed to improve accuracy, increase reliability, and simplify operation, the P3860-BAR can be used to calibrate virtually any high pressure sensing device including transducers, transmitters, gauges or pressure switches.

Instrument Base

The Instrument base includes all items required for operation. A high quality hand pump is coupled to a 7 to 1 intensifier, allowing the operator to easily generate high pressure in the system. An oil reservoir is included so that the pump can be recharged when calibrating large volume devices. A Test Station is provided for connecting the Device under Test to the P3860-BAR. Adjustable feet and the level vial allow the operator to ensure that the instrument is level, in order to achieve the ultimate performance. A Piston Float Reference allows the operator to determine when the piston is in the ideal, "mid float" position.

Piston/Cylinder

The piston/cylinder is the "heart" of the deadweight tester. P3860-BAR pistons are manufactured from tungsten carbide which provides excellent long term stability, durability, and extremely low coefficients for temperature and pressure.

Weight Sets

Standard weight masses are series 3 non-magnetic stainless steel. Each mass is marked with the serial number of the instrument and the nominal pressure value. PressCal software can be used to support additional pressure units.

Gravity Correction

Gravity varies significantly with geographical locations. Each instrument can be calibrated to local gravity at no additional cost. If unspecified, instruments are calibrated to standard gravity at 980.665 cm/s2.
