Wika Model CPB3800 Dead-weight Tester (Compact design)

Due to its integrated pressure generation and the purely mechanical measuring principle, the model CPB3800 is ideal for on-site use for maintenance and service.

Pressure is defined as the quotient of force and area. The core component of the CPB3800 is therefore a very precisely manufactured piston-cylinder system, onto which a mass load is applied in order to generate the individual test points. 

The mass load is proportional to the target pressure and this is achieved through optimally graduated masses. As standard, these masses are manufactured to the standard gravity (9.80665 m/s²), though they can be adjusted to a specific location and calibrated according to UKAS accreditation.

Special features

■ Total measurement uncertainty up to 0.025 % of reading 

■ Upgradeable using CPS5800/CPM5800 to provide increased accuracy to 0.006 % 

■ Direct replacement of original DH-Budenberg 580 series 

■ Factory calibration included as standard, traceable to national standards, with UKAS calibration possible as an option 

■ Masses manufactured from stainless steel, can be adjusted to local gravity

Applications

■ Primary standard for calibrating the pressure scale in a hydraulic range up to 1,200 bar [16,000 lb/in²] 

■ Reference instrument for factory and calibration laboratories for the testing, adjustment and calibration of pressure measuring instruments 

■ Complete, stand-alone system, also suitable for on-site use
