Description

Basic principle

Pressure is defined as the quotient of force and area (P= F/A). Correspondingly, the core of the CPB 5000HP is a very precisely-manufactured piston cylinder system, which is loaded with masses 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.

The pressure is set via an integrated pump. 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.

The excellent quality of the system ensures that this pressure remains stable over several minutes, so that the device under test can be calibrated or time-consuming adjustments can be carried out without any problems.

Solid instrument design

The CPB5000HP has been designed around a solid platform and offers exceptional ease-of-use. With the integrated initial pressure pump and 250 ml tank, large test volumes can also be easily filled and pre-compressed.

Measuring ranges

• 2500 bar / 40000 psi
