High Pressure Deadweight Tester
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.

Accuracy (measurement uncertainty): ±0.020% or ±0.025% of measured value.

 

Applications:

 

  • Reference instrument for the calibration of pressure measuring instruments
  • Primary pressure standard for calibration laboratories and factory, for the testing, adjustment and calibration of pressure measuring instruments, for defining the pressure scale in a range up to 5,000 bar
  • Complete stand-alone system, also suitable for on-site use

Features:

 

  • Total measurement uncertainty to 0.02% of measured value
  • Range 2,600 bar with dual-range piston-cylinder system with fully automated changing between ranges
  • Including factory calibration certificate; DKD-/DAkkS certificate as option
  • High long-term stability with recommended recalibration cycle every 5 years
  • Masses made from stainless steel and aluminum, can be manufactured to local gravity

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.

Description

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.
