Basic principle
Pressure is defined as a quotient of force and area (P= F/A). Correspondingly, the core of the CPB 5000 is a very precisely manufactured piston cylinder system, which is weighted with mass-loads in order to generate the individual test points.
These weights are manufactured to standard gravity (9.80665 m/s²) although for fixed location usage they can be adjusted to a customer specified local gravity.
Easy functioning
Depending on the instrument version the pressure is set via an integrated pump or via an external pressure supply by the use of control valves. For fine adjustment a very precisely adjustable spindle pump is mounted. As soon as the measuring system reaches equilibrium, there is a balance of forces between pressure and mass applied. Due to the excellent quality of the system this pressure remains stable over several minutes, so that the device under test can be calibrated or instance adjustments can be carried out without any problems.
