Pressure standards (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 standard (dead-weight tester) has therefore been used for years in factory and calibration laboratories in industry, national institutes and research laboratories.
Due to its integrated pressure generation and the purely mechanical measuring principle, the pressure standard model CPB3800 is ideal for on-site use for maintenance and service.
Pressure is defined as the quotient of force and area. The core component of the pressure standard 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 andcalibrated according to UKAS accreditation.
