Hydraulic deadweight tester CPB5000HP

Primary standard for defining the pressure scale in a hydraulic range up to 5,000 bar (70,000 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 Total measurement uncertainty to 0.02 % of reading Factory calibration includes traceability to national standards, as standard; with DKD/DAkkS calibration possible as an option High long-term stability with recommended recalibration cycle every five years Masses manufactured from stainless steel and aluminium, can be adjusted to local gravity Description Proven primary standard Pressure balances (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 balance (dead-weight tester) has therefore been used for years in factory and calibration laboratories in industry, national institutes and research laboratories. Stand-alone operation Due to its integrated pressure generation and the pure mechanical measuring principle, the model CPB5000HP is ideal for on-site use for maintenance and service. Basic principle Pressure is defined as the quotient of force and area. The core component of the CPB5000HP is therefore a very precisely-manufactured piston-cylinder system,
