Description
Mature benchmarks
Piston pressure gauges are the most accurate instruments on the market for calibrating electronic or mechanical pressure gauges, measuring pressure directly (P = F/A). The balance is manufactured from high quality materials, minimizing measurement uncertainty and providing long-term stable operation. Due to the above characteristics, this type of pressure balance has been used in the calibration laboratories of the factory and industry, national institutions and research laboratories for many years.
Run independently
The CPB3800 features an integrated pressure source and pure mechanical measurement principle, making it ideal for on-site maintenance and overhaul.
Basic principles
Pressure is the pressure within a unit area. Based on this, the CPB3800 uses a precision-engineered piston-cylinder system as the core component to generate individual test points by loading weight groups.
The weight group is best divided into different quality levels, so that the weight of the load on the balance is proportional to the target pressure. By standard, these weights are manufactured to standard gravity (9.80665 m/s²), but users can also adjust to local gravity and UKAS calibration.
