Description
Reference primary standards
Pressure balances are high-precision fundamental pressure standards that define the derived unit of pressure directly from the base units of mass, length and time following the formula p = F/A. The direct measurement of the pressure with a pressure balance in combination with the know-how of DH-Budenberg guarantees the best metrological specifications on the market.
- High-quality piston-cylinder systems (high floating time and long-term stability)
- Protection and smooth handling of the mass set
This type of pressure balance has been successfully tested by national institutes, calibration laboratories and all type of industries.
Large-volume calibration
The CPB9500 has been developed to not only provide the best possible metrological specifications, but also to meet the requirements of the industry.
Thanks to the high MTBF values, the pressure generation system of the CPB9500 can also generate and control pressures for large test volumes.
Automation and metrology
The servo-controlled spindel pump for pressure generation, combined to the built-in optical detection used to measure the piston position, offers fine and reliable pressure regulation. The mass set protected in a rack is handled carefully providing the highest stability. Finally the pressure is automatically fully corrected taking in account all ambient parameters.
The CPB9500 is available with a hydraulic fine increment mass handling system. For optimal fulfilment of special requirements, a wide range of piston-cylinder systems is available.
