Applications

• Primary standard for the calibration of differential pressure measuring instruments under static pressure
• 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

• Measuring ranges (= static pressure + differential pressure) up to 400 bar (5,000 psi) pneumatic, up to 1,600 bar (23,200 psi) hydraulic
• Total measurement uncertainty to 0.008 % of differential pressure plus 0.0001 % (1 ppm) of static pressure
• 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

Description

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.
