Hydraulic deadweight tester CPB5000-HP

Reference instrument for the calibration of pressure measuring instruments Primary pressure standard for calibration laboratories and factory, for the testing, adjustment and calibration of pressure measuring instruments, for defining the pressure scale in a range up to 5,000 bar Complete stand-alone system, also suitable for on-site use Features: Total measurement uncertainty to 0.02% of measured value Range 2,600 bar with dual-range piston-cylinder system with fully automated changing between ranges Including factory calibration certificate; DAkkS certificate as option High long-term stability with recommended recalibration cycle every 5 years Masses made from stainless steel and aluminium, can be manufactured to local gravity Proven primary pressure standard Deadweight Tester / Pressure Balances are the most accurate instrument 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 of 5 years (recommended in accordance with German Calibration Service DKD/DAkkS). The deadweight tester / pressure balance has therefore been used for years in factory and calibration laboratories in national institutes, research laboratories and in industry. Stand-alone operation Due to its integrated pressure generation and the pure mechanical measuring principle, the model LR-Cal CPB5000-HP 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
