High Pressure Balance
Model CPB5000-HP
Deadweight Tester (Pressure Balance, Primary Pressure Standard), hydraulic, Ranges from 25...2,500 bar to 25...5,000 bar and 350...40,000 psi to 350...70,000 psi or with dual piston system with range 1...2,600 bar / 10...40,000 psi.

Ø Theoretical starting value; corresponds to the pressure value generated by the piston (by its own weight). To optimize the operating characteristics, more weights should be loaded.
Ø The smallest pressure change value that can be achieved based on the standard weight set. To reduce this, a set of trim-masses is available (see accessories).
Ø The accuracy from 10% of the measuring range is based on the measured value. In the lower range, a fixed error based on 10% of the range applies.
Ø Measurement uncertainty assuming reference conditions (ambient temperature 20°C, air pressure 1,013 mbar, relative humidity 40%). For operation without an Intelligent Calibration Modulel LR-Cal IKM corrections must be made if required.

LDW-FMS-F1
|
The weights included in the standard mass set are ideally suited for everyday use. If smaller intermediate values need to be generated, we recommend using a set of trim-masses.
Trim-mass set, class F1 (1 x 50 g, 2 x 20 g, 1 x 10 g, 1 x 5 g, 2 x 2 g, 1 x 1 g, 1 x 500 mg, 2 x 200 mg, 1 x 100 mg, 1 x 50 mg, 2 x 20 mg, 1 x 10 mg, 1 x 5 mg, 2 x 2 mg, 1 x 1 mg
