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 pure mechanical measuring principle, the model CPB5000HP 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 CPB5000HP 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 DKD/DAkkS calibrated.
