Deadweight Tester (Pressure Balances)
are the most accurate instruments for the calibration of electronic or
mechanical pressure measuring instruments. The direct measurement of
pressure, according to its definition as a quotient of force and area, and
the use of high-quality materials result in small uncertainties of
measurement and an excellent long-term stability of five years. For these
reasons, deadweight testers have already been used in calibration
laboratories of industry, national institutes and research labs for many
years.
Due to the integrated pressure generation and the purely
mechanical measurement principle, the
CPB5000-HP deadweight
testers are ideally suited for on-site use as well as service and
maintenance purposes.
The core of the
CPB5000-HP is a piston/cylinder
system of special material. Besides this high-quality material, which
primarily stands out for its small temperature coefficient, the
workmanship of the system is a measure of the final accuracy of the
pressure balance. Several refinement processes ensure a high-quality and
even surface with small graps of only a few micrometer.
In order to generate the individual test points, the piston/cylinder system
is weighted with mass-loads, which are also calibrated and specially adapted
to the respective application. The pressure is set via the integrated pump.
For fine adjustment an adjustable volume with precision spindle is
available. The weight applied is proportional to the desired pressure and
provided by using optimally graduated weights. As soon as the measuring
system reaches quilibrium, there is a balance of forces between pressure and
wheel weights. Due to the excellent quality of the system this pressure
remains stable over several minutes, so that for instance adjustments of
your device under test can be carried out without any problems.

Accuracy (uncertainty):
±0.025% of measured value (%RD). The accuracy is characterized by the deviation
span, which is the sum of the systematic error and the uncertainties of
measurement. Long-term stability is not taken into account. Please note that
corrections might be required if the instrument is used without the optional
Intelligent Calibration Module - see operating manual.
As an option, systems with increased accuracies up to 0.02% of reading are
available
