Basic principle
Pressure is defined as the quotient of force and area (P = F/A). The core component of the CPB3800 is therefore a very precisely-manufactured piston-cylinder system, which is loaded with masses in order to generate the inpidual test points.
As standard, the masses are manufactured to the standard gravity (9.80665 m/s²), though they can be adjusted to a specific location.
Easy operation
The integrated dual-area pump enables rapid filling of the test system and smooth pressure generation up to 1,200 bar. A control schematic for pressure generation on the instrument base facilitates quick and easy operation. |
As soon as the measuring system reaches equilibrium, there is a balance of forces between the pressure and the mass load 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 that more complex adjustments can be carried out on the item under test
Compact and self-contained
The CPB3800 is also particularly notable for its compact dimensions. With its exceptionally robust ABS plastic housing and the low weight associated with these, the CPB3800 is also particularly suited to on-site applications. |
