Pneumatic deadweight tester CPB5000

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. Applications of the pressure balance Primary standard for defining the pressure scale in a pneumatic range of up to 100 bar (1,500 psi) or with a gas to oil separator up to 400 bar (5,000 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 balance 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
