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.
The differential pressure deadweight tester
CPB5000-DP allows a real calibration of differential pressures,
based on static line pressure.
The
CPB5000-DP includes two common pressure
balances of the basic series
CPB5000. For the
calibration of differential gauges at a static line pressure, the system can
be separated (via bypass-valve).
One system is used to generate the line pressure. The second one supplies
the differential pressure (including line pressure).
For the basic specification, see type
CPB5000.
Optional Accessories
- Set of trim-masses for generating intermediate values
(weights 1 mg to 50 g)
- Oxytester (Purifier) for measuring instruments where
the filling medium should not come into contact with the deadweight
tester
- Dirt trap for test objects that are very dirty in order
to avoid the penetration of dirt particles into the deadweight tester
- Set of adapters in a tool case with 5 most commonly
used threaded adapters and a spanner (flats 32 and flats 14)
- Cleaning Kit "CPB5000-PN-RS" for pneumatic pistons
- Cleaning Kit "CPB5000-HY-RS" for hydraulic pistons

Accuracy (uncertainty):
±0.015% 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 0.008% of reading are
available
| Recommended accessory:
Hand Suction Pump HAP 02
Datasheet
for suction of fluids, e.g. oil, water, break fluid, etc.
Perfect for the suction of the operation fluid of deadweight
tester (e.g. before transport etc.). |
