The Pressurements 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.
Options
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 |
|
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. |
