Pneumatic deadweight tester CPB5000

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 0.008 % of reading Factory calibration included as standard, traceable to national standards; with DKD/DAkkS calibration possible as an option High long-term stability with recommended recalibration interval every five years Masses manufactured from stainless steel and aluminium, can be adjusted to local gravity Quick and safe replacement of the piston-cylinder system for measuring range changes via patented ConTect quickrelease system as an option 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 purely mechanical measuring principle, the model CPB5000 is ideal for on-site use for maintenance and service.
