Description
Proven primary standard
Pressure balances are the most accurate instruments for the
calibration of electronic or mechanical pressure measuring
instruments. The direct measurement of pressure, (P = F/A)
and the use of high-quality materials, result in small measurement uncertainties and an excellent long-term stability of five
years (Recommendation in accordance with the German
Calibration Service DKD/DAkkS).
For these reasons pressure balances have already been
used in the calibration laboratories of industry, national institutes and research laboratories for many years.

Basic principle
Pressure is defined as the quotient of force and area. Correspondingly, the core of the CPB5000-HP is a very preciselymanufactured piston cylinder system, which is loaded with
masses in order to generate the individual test points.
The weight applied is proportional to the desired pressure
and accomplished by using optimally graduated weights.
These weights are manufactured to standard gravity
(9.80665 m/s²) although, for fixed location usage, they can
be adjusted to a customer-specified local gravity.

Self-contained operation
Due to the integrated pressure generation and the purely
mechanical measuring principle, the CPB5000-HP is ideally
suited to on-site use as well as service and maintenance
purposes.
