Wika Model CPB5800 Hydraulic Pressure Balance

Pressure balances (dead-weight testers) are the most accurate instruments available on the market for the calibration of electronic or mechanical pressure measuring instruments.

Due to its integrated pressure generation and the purely mechanical measuring principle, the model CPB5800 is ideal for on-site use for maintenance and service.

Basic principle Pressure is defined as the quotient of force and area. The core component of the CPB5800 is therefore a very precisely manufactured piston-cylinder system, onto which a mass load is applied in order to generate the individual test points.

Special features

■ Total measurement uncertainty to 0.006 % of reading 

■ Extremely flexible instrument with a wide range of single and dual-range piston-cylinder systems 

■ Dual-range piston-cylinder systems with fully automated changing between ranges 

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

■ Fast and safe replacement of the piston-cylinder system via patented ConTect quick-release system as an option

Applications

■ Primary standard for calibrating the pressure scale in a hydraulic range up to 1,400 bar [20,000 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
