DH-Budenberg CPB3500 Pneumatic Deadweight Tester


- +


The CPB3500 is a genuine primary standard, which derives the measurement of pressure directly from its fundamental equation p = F/A. This mechanical measurement principle provides superior reliability and stability over time, eliminates most risks of measurement error and reduces calibration uncertainties. It makes the CPB3500 the ideal tool for the calibration of any type of pressure measuring instruments on a daily basis.

The DH-Budenberg CPB3500 is built on a tough, stable aluminum base with light weight corrosion and impact-resistant ABS case. Piston cylinders are interchangeable among the various models within the CPB3500, so that in case of changing requirements any CPB3500 tester can easily be upgraded on other available ranges.

Mass sets are fully interchangeable between pistons of the same range within the claimed standard accuracy. The mass set is made of non-magnetic stainless steel so that masses remain extremely stable over time. Bases can also be quickly converted into a comparator by substituting suitable transfer standard for the piston and mass set.

Two built-in precision soft seat valves combined with a volume adjuster provide fine pressure control capability. A safety pattern gauge is fitted to the instrument base to show the approximate pressure. The masses are top loading (except on the 25 bar/400 psi range) for easier and faster operation and available in the most common pressure units.
