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/s?) although,   for fixed location usage they can be adjusted to a customer-specified local   gravity.  
  
Easy operation  
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  
4000 bar / 60000 psi  
5000 bar / 70000 psi
