   Description


   Proven primary standard
    Pressure balances 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 of five years (recommended in accordance with the
German Calibration Service DKD/DAkkS). The pressure balance 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 pure mechanical measuring principle, the model CPB5800 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 CPB5800 is therefore a very precisely-manufactured piston-cylinder system, which is
loaded with masses in order to generate the individual test points.
    The masses applied are 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 UKAS or DKD/DAkkS calibrated.
