Calibration technology WIKA data sheet CT 31.07 Dead-weight tester, high-pressure version, model CPB3800HP Applications ■ Primary standard for calibrating the pressure scale in a hydraulic range up to 2,600 bar ■ 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 Special features ■ Total measurement uncertainty up to 0.007 % of reading ■ Dual-range piston-cylinder system 2,600 bar with fully automated changing between ranges ■ Factory calibration includes traceability to national standards, as standard, 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 pure mechanical measuring principle, the model CPB3800HP 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 CPB3800HP is therefore a very precisely manufactured piston-cylinder system, which is loaded with masses in order to generate the individual test points. The masses applied are 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 also UKAS calibrated.

Easy operation The integrated dual-area spindle pump enables rapid filling of the test system and smooth pressure generation up to 2,600 bar. 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 mass load applied. The excellent quality of the system ensures that this pressure remains stable over several minutes, so that the pressure...

1) Theoretical starting value; corresponds to the pressure value generated by the piston or the piston and its make-up weights (by their own weight). To optimise the operating characteristics more masses should be loaded. 2) The smallest pressure change value that can be achieved based on the standard mass set. To reduce this, a set of fine increment masses is also available. 3) The accuracy from 10 % of the measuring range is based on the measured value. In the lower part the accuracy is 0.025 % of reading. 4) Measurement uncertainty assuming reference conditions (ambient temperature 20...

CalibratorUnit model CPU6000 The models of the CPU6000 series are compact tools for use with a pressure balance (dead-weight tester). In particular when highly accurate measuring values, with measurement uncertainties of less than 0.025 %, are required, complicated mathematical calculations and corrections are necessary. With the CPU6000 in combination with the CPB-CAL (iPad® app) and/or WIKA-CAL (PC software) all critical ambient parameters can be registered and automatically corrected. The CPU6000 series is made up of three instruments Weather station, model CPU6000-W The CPU6000-W...
