Fluke P3830 High Pressure Hydraulic Deadweight Tester
The Pressurements P3800 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 P3800 series can be used to calibrate virtually any high pressure sensing device including transducers, transmitter, 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 the pump to be recharged when calibrating large volume devices. A Test Station is provided for connecting the Device under Test to the P3800 Series. Adjustable feet and the level vial allow the operator to insure the instrument is level 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 dead-weight tester. The P3800 Series pistons are manufactured from tungsten carbide which provides excellent long term stability, durability, and extremely low coefficients for temperature and pressure.
Weight set:
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. Select either psi, bar, or MPa pressure units. PressCal software can be used to support additional pressure units.
| Pressure Ranges | |
| P3830 | 500 psi to 30 000 psi, or 40 bar to 2 000 bar, or 4 MPa to 200 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 certificate. Below 10%, ± (accuracy class) x 10% of the piston range. |
