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.

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.

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
