Description
Reference primary standards
Pressure balances are high accuracy 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 an automatic balance combined to the know-how of Desgranges & Huot guarantees the best metrological specifications on the market.
High quality piston-cylinder units (high floating time, long term stability)
Protection and smooth handling of the mass set
Large volume calibration
CPB8000 has been designed to provide the best available metrological specifications but also to reply to industry expectations. 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 variable volume pressure generator combined to the built-in optical detection used to measure the piston position offer 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.
High-performance instrument range
The model CPB8000 is available in 4 variants:
pneumatic or hydraulic pressure generation
with or without the trim mass set handling system (down to 10 mg)
A large range of piston-cylinder assemblies is available to best meet your specific requirements.
