The P3800 Series High Pressure Hydraulic Deadweight Testers are the culmination of over 50 years of experience in the production and design of high performance 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, transmitters, gauges, pressure switches or other calibrators.

Three models are available, P3830, P3840 and P3860 offering pressure ranges of 30,000, 40,000 and 60,000 psi respectively (2000, 3000 and 4000 bar). All models are available in two accuracy classes, 0.02% or 0.015% of Reading. The Series P3800 offers an accurate and economical approach to calibrating high pressure devices.

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 re-charged 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.

Pressure Ranges 
P3830 500 to 30,000 psi, or 40 to 2,000 bar, or 4 to
200 MPa, or 40 to 2000 kgf/cm2
P3840 500 to 40,000 psi, or 40 to 2,600 bar, or 4 to
260 MPa, or 40 to 2600 kgf/cm2
P3860 500 to 60,000 psi or 40 to 4,000 bar or 4 to
400 MPa or 40 to 4000 kgf/cm2
Accuracy Standard accuracy is 0.02% of Reading*. Optional accuracy of 0.015% of Reading is available. ISO/IEC 17025 accredited calibration is provided with each instrument. *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. See the “Guide for the Uncertainty Analysis in Pressure when Using P3000 Series Deadweight Testers” technical note for more information.
