Mechanical pressure gauges are exposed to natural ageing and environmental influences during operation. Over time, these influences can lead to measurement deviations in the display. Regular verification is necessary to ensure high measurement accuracy and process reliability in the long term.
Bourdon tube pressure gauges are robust and are used to display and measure high pressures.
For verification, the RT 305.08 Bourdon tube pressure gauge is connected pneumatically to the RT 304 calibration stand via quick-release couplings.
The test points are set using a precision pressure regulator and compared with a reference pressure gauge across the entire measuring range. The deviations are recorded.
