Overview
IEC 63041-3:2020 is an international standard issued by the International Electrotechnical Commission (IEC) that focuses on piezoelectric physical sensors. This part of the IEC 63041 series applies particularly to sensors used for measuring and detecting various physical quantities. It is highly relevant for sectors such as process control, wireless monitoring, thermodynamics, vacuum engineering, dynamics, and environmental sciences.
The document provides both foundational knowledge and technical guidelines for the use of piezoelectric sensors in physical measurement scenarios. Covered sensor types include those detecting force, pressure, torque, viscosity, temperature, film thickness, acceleration, vibration, and tilt angle. The standard addresses essential aspects such as terminology, specifications, quality, reliability, and common measurement procedures.
