The Fluke Calibration P3800 Pressurements Series 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 Fluke Calibration P-3800 Series can be used to calibrate virtually any high pressure sensing device including transducers, transmitters, gauges or pressure switches.

Instrument base
The Instrument base of the Fluke Calibration P3800 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 the pump to be recharged when calibrating large volume devices. A Test Station is provided for connecting the Device under Test to the Fluke Calibration P/3800 Series. Adjustable feet and the level vial allow the operator to insure the instrument is level to achieve the ultimate perfor-mance. A Piston Float Reference allows the operator to deter-mine when the piston is in the ideal, "mid float" position.

Piston/cylinder
The piston/cylinder is the "heart" of the deadweight tester. The Fluke Calibration P3800 Series pistons are manufactured from tung-sten carbide which provides excellent long term stability, durability, and extremely low coefἀcients for temperature and pressure.

Weight sets
Standard weight masses are series 3 non-magnetic stain-less steel. Each mass is marked with the serial number of the Fluke Calibration P3800 instrument and the nominal pressure value. Select either psi, bar or MPa pressure units. PressCal software can be used to support additional pressure units.

Gravity correction
Gravity varies significantly with geographical locations. Each Fluke Calibration P-3800 instrument can be calibrated to local gravity a no additional cost. If unspecified, the Fluke Calibration P3800 instruments are calibrated to standard gravity at 980.665 cm/s2.

Pressure ranges
P3830 500 psi to 30,000 psi, or 40 bar to 2 000 bar, or 4 MPa to 200 MPa
P3840 500 psi to 40,000 psi, or 40 bar to 2 600 bar, or 4 MPa to 260 MPa
P3860 500 psi to 60,000 psi or 40 bar to 4 000 bar or 4 MPa to 400 MPa
Accuracy Standard accuracy is 0.02 % of Reading*. Optional accuracy of 0.015 % of Reading is available. ISO/IEC 17025 accredited calibration certificate is standard
*Accuracy is based on % of Reading from 10% to 100% of the piston range when used in accordance with the corrections found on the calibration certiἀcate. Below 10%, ± (accuracy class) x 10% of the piston range.
