Description
References
Piston pressure gauge is a high-accuracy basic pressure standard, which can be defined by the p = F / A formula directly from the basic unit of mass, length and time.
The piston pressure gauge combines Desgranges & Huot's expertise to directly measure pressure and achieve the best metering specifications on the market.
High quality piston cylinder unit (long floating time, long-term stability)
Aluminum cast housing and rugged components (minimum maintenance and overhaul)
CPB6000DP is specifically designed for differential pressure calibration under high static line pressure conditions, integrating two pneumatic piston cylinders in one housing.
The CPB6000DP piston consists of two CPB6000-PX piston cylinders:
integrated into a box for easy operation
Built-in pressure control
The other side of the CPB6000DP can be used as a CPB6000-PX for pressure gauge calibration
