Overview
SIST EN IEC 63041-3:2026 - Piezoelectric sensors – Part 3: Physical sensors is an internationally recognized standard developed by the European Committee for Electrotechnical Standardization (CLC) and the International Electrotechnical Commission (IEC). This standard provides technical guidelines and essential information on piezoelectric physical sensors, particularly those utilized in process control, wireless monitoring, dynamics, thermodynamics, vacuum engineering, and environmental sciences.
This document serves both as a technical reference and as a practical resource for understanding the selection, application, and specification of piezoelectric sensors used to detect and measure physical quantities such as force, pressure, torque, viscosity, temperature, film thickness, acceleration, vibration, and tilt angle. SIST EN IEC 63041-3:2026 supersedes the 2020 edition and includes updated terminology in alignment with IEC TS 61994-5:2023.
