Description

Applications:
  • Primary standard for calibrating the pressure scale in a hydraulic range up to 1,200 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 to 0.025% of reading
  • Upgradeable using CPS5800/CPM5800 to provide increased accuracy to 0.006%


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 testers) 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 about the pure mechanical measuring principle, the model CPB3800 is ideal for on-site use for maintenance and service.

Basic PrinciplePressure is defined as the quotient of force and area. The core component of the CPB3800 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 priming of the test system and smooth pressure generation up to 1,200 bar. At the same time, the precise 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 valve for comparative measurements can be read without any problems, or also so that more complex adjustments can be carried out on the item under test.
