Messtechnik

Messtechnik, or measurement technology, is the discipline that deals with the design, construction, calibration, and use of instruments and systems for acquiring quantitative information about physical quantities. It covers the measurement of length, mass, time, temperature, pressure, electrical quantities, chemical concentrations, flow, and many other parameters across science and industry. The central aim is to obtain accurate, reliable results with well-characterized uncertainty.

A measurement chain typically includes sensors or transducers that convert a quantity into a signal, signal conditioning, data acquisition hardware, and data analysis or visualization software. Metrology provides the scientific basis, emphasising traceability to international or national standards, calibration procedures, and the estimation and reporting of measurement uncertainty. Primary standards or references define SI units or physical phenomena, while secondary standards ensure consistency across instruments.

Measurement technology supports manufacturing and quality control, process monitoring, instrumentation for automotive and aviation, energy systems, environmental monitoring, medical devices, and scientific research. It comprises static (steady-state) and dynamic measurements, contact methods (gauges, thermocouples) and non-contact methods (optical, laser, infrared), as well as advanced techniques such as digital signal processing and calibration management.

Standards and institutions shape the field. National metrology institutes develop and maintain references and standards; international bodies coordinate unit definitions and comparability. Compliance with standards and calibration certificates underpins reliable measurements in industry and science.
