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 material 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 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, 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

In stable instrument base, the integrated priming pump and the 250 ml tank enable large test volumes to be easily filled and pressurized. For further pressure increases and fine adjustment, a very precisely-controllable spindle pump is fitted, which only runs within the pump body. 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 value 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.
