Dead-weight tester in compact design Model CPB3800 data sheet
■Proven primary standard
▲Pressure balances (dead-weight testers) are the most accurate instruments available on the market for the calibration of electronic or mechanical pressure measuring instruments. The direct measurement of the pressure (p = F/A), as well as the use of high-quality materials enable a very small measurement uncertainty, in conjunction with an excellent long-term stability.
▲The pressure balance (dead-weight tester) has therefore been used for years in factory and calibration laboratories in industry, national institutes and research laboratories.
■Stand-alone operation
▲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.
■Basic principle
▲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
