Hydraulic deadweight tester CPB3800

Proven primary standard Pressure standards (dead-weight testers) are the most accurate instruments available on the market for the calibration of electronic or mechanical pressure measuring instruments. The direct measurement of the pressure (p = F/A), as well as the use of high-quality materials enable a very small measurement uncertainty, in conjunction with an excellent long-term stability. The pressure standard (dead-weight tester) has therefore been used for years in factory and calibration laboratories in industry, national institutes and research laboratories. Applications of the pressure standard Primary standard for calibrating the pressure scale in a hydraulic range up to 1,200 bar (16,000 psi) Reference instrument for factory and calibration laboratories for the testing, adjustment and calibration of pressure measuring instruments Complete, stand-alone system, also suitable for on-site use Special Features of the pressure standard Total measurement uncertainty up to 0.025 % of reading Upgradeable using CPS5800/CPM5800 to provide increased accuracy to 0.006 % Direct replacement of original DH-Budenberg 580 series Factory calibration included as standard, traceable to national standards, with UKAS calibration possible as an option Masses manufactured from stainless steel, can be adjusted to local gravity
