■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
■Description
●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.
●Easy operation
▲The integrated dual-area spindle pump enables rapid filling of the test system and smooth pressure generation up to 1,200 bar [16,000 lb/in²]. At the same time, the precisely adjustable spindle pump also enables fine pressure adjustment. 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 masses. 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 so that more complex adjustments can be carried out on the test item.
●Compact instrument version
▲The CPB3800 is also particularly notable for its compact dimensions, which are not altered during operation, since the spindle runs within the pump body.With its compact dimensions, the exceptionally robust ABS plastic case and the low weight associated with these, the CPB3800 is also particularly suited to on-site applications.
