proven primary standard
   pressure balances are the most accurateinstrumentsavailable on the market for the calibration ofelectronic ormechanical pressure measuring instruments. the directmeasurementof the pressure (p = f/a), as well as the use ofhigh-qualitymaterials enable a very small measurement uncertainty,inconjunction with an excellent long-term stability of fiveyears(recommended in accordance with german calibrationservicedkd/dakks).the pressure balance has therefore been used foryearsin factory and calibration laboratories in industry,nationalinstitutes and research laboratories.
  stand-aloneoperation
   due to its integrated pressuregeneration and the puremechanical measuring principle, the modelcpb5600dp is ideal foron-site use for maintenance andservice.
basicprinciple
   pressure is defined as the quotient of force andarea.the core component of the cpb5600dp is therefore averyprecisely-manufactured piston-cylinder system, which is loadedwithmasses in order to generate the individual test points.
   the masses applied are proportional to thetargetpressure and this is achieved through optimally graduatedweights.as standard, these masses are manufactured to the standardgravity(9.80665 m/s²), though they can be adjusted to a specificlocationand also dkd/dakks calibrated.
