High Pressure Deadweight Tester CPB5000-HP

Product Description

Proven primary standard

Pressure balances are the most accurate instruments for the calibration of electronic or mechanical pressure measuring instruments. The direct measurement of pressure, (P = F/A) and the use of high-quality materials, result in small measurement uncertainties and an excellent long-term stability of five years (Recommendation in accordance with the German Calibration Service DKD/DAkkS). For these reasons pressure balances have already been used in the calibration laboratories of industry, national institutes and research laboratories for many years.

Self-contained operation

Due to the integrated pressure generation and the purely mechanical measuring principle, High Pressure Deadweight Tester CPB5000-HP is ideally suited to on-site use as well as service and maintenance purposes

Basic principle

Pressure is defined as the quotient of force and area. Correspondingly, the core of High Pressure Deadweight Tester CPB5000-HP is a very precisely manufactured piston cylinder system, which is loaded with masses in order to generate the individual test points. The weight applied is proportional to the desired pressure and accomplished by using optimally graduated weights. These weights are manufactured to standard gravity (9.80665 m/s²) although, for fixed location usage, they can be adjusted to a customer-specified local gravity.
