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

Description of the pressure balance

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.
