Druckstandards

Druckstandards, or pressure standards, are established reference values used to ensure accurate and consistent pressure measurements across various industries and scientific applications. These standards form the basis for calibrating pressure instruments, enabling reliable data comparison globally. Their importance spans fields such as meteorology, aviation, medicine, and manufacturing, where precise pressure control is critical for safety and performance.

Pressure standards are typically categorized by the method used to generate the reference pressure. Primary standards, like dead-weight testers or mercury manometers, are based on fundamental physical principles and provide the highest level of accuracy for calibrating other standards. Secondary standards, such as high-precision electronic pressure sensors, are calibrated against primary standards and are more commonly used in industrial settings for routine calibrations.

International and national metrology institutes, such as the International Bureau of Weights and Measures (BIPM), maintain and define these standards. They ensure traceability, meaning any measurement can be linked back to a primary standard through an unbroken chain of comparisons. This traceability is a cornerstone of quality assurance systems. Common pressure units defined by these standards include the pascal (Pa), bar, and pounds per square inch (psi). By adhering to druckstandards, organizations guarantee that their pressure measurements are trustworthy, repeatable, and internationally recognized.
