Description  Basic principle  
  
Pressure is defined as the quotient of force and area (P= F/A). The core   component of the CPB5800 is therefore a very precisely-manufactured   piston-cylinder system, which is loaded with masses in order to generate the   individual test points.  
As standard, these masses are manufactured to the standard gravity (9.80665   m/s2), though they can be adjusted to a specific location.  
  
Easy operation  
The integrated priming pump and the 250 ml tank enable large test volumes to   be easily filled and pressurised. For further pressure increases and fine   adjustment, a very precisely-controllable spindle pump is fitted.  
As soon as the measuring system reaches equilibrium, there is a balance of   forces between the pressure and the mass loads applied. The excellent quality of   the system ensures that this pressure remains stable over several minutes, so   that the pressure value for comparative measurements can be read without any   problems, or also so that more complex adjustments can be carried out on the   item under test.  
High-performance instrument range  
The CPB5800 instrument base is available in 2 variants:  
  
Standard hydraulic base    
  
  up to max. 1,200 bar / 16,000 psi  
with integrated pressure generation through  priming pump and spindle   pump  
Standard pressure transmission medium: mineral oil, optional: Sebacate oil,   brake fluid, Skydrol, Fomblin oil or water    
  
Hydraulic high-pressure base    
  
up to max 1,400 bar / 20,000 psi  
with integrated pressure generation through priming pump and spindle   pump  
Pressure transmission medium: mineral oil or Sebacate oil
