Pressure balance

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. Basic principle Pressure is defined as the quotient of force and area. The core component of the pressure balance CPB5000 is therefore a very precisely manufactured piston-cylinder system, onto which a mass load is applied in order to generate the individual test points. The mass load is proportional to the target pressure and this is achieved through optimally graduated masses. As standard, these masses are manufactured to the standard gravity (9.80665 m/s²), though they can be adjusted to a specific location and also DKD/DAkkS calibrated.
