Automatic pressure balance CPB8000

Reference primary standards
Pressure balances are high-precision fundamental pressure standards that define the derived unit of pressure directly from the fundamental units of mass, length and time following the formula p = F/A.
The direct measurement of the pressure with a pressure balance combined to the know-how of Desgranges & Huot guarantee 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
CPB8000 has been designed to provide the best available metrological specifications but also to respond to industry requirements. Providing a high MTBF, the CPB8000 pressure generation system can also generate and regulate with large volume under test.

Automation and metrology
The servo-controlled spindle 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 cabinet is handled carefully providing the highest stability. Finally the pressure is automatically fully corrected taking in account all ambient parameters.

Our models
CPB8000 is available in four versions: pneumatic or hydraulic pressure, with or without the trim mass set handling system (optional down to 10 mg). A large range of piston-cylinder systems is available to best meet your specific requirements.
