Description
Proven primary standard
Pressure balances (dead-weight testers) are the most accurate instruments available on the market. They are used for the calibration of electronic or mechanical pressure measuring instruments.
Features
- Direct measurement of the pressure (p = F/A)
- Use of high-quality materials
- Very small measurement uncertainty
- Excellent long-term stability
- 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 purely mechanical measuring principle, the model CPB5000 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 pressure balance CPB5000 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 and also DKD/DAkkS calibrated.
