IEC 63041-3-2020 pdf download.Piezoelectric sensors – Part 3: Physical sensors.
This part of IEC 63041 is applicable to piezoelectric physical sensors mainly used in the field of process control, wireless monitoring, dynamics, thermodynamics, vacuum engineering, and environmental sciences. This document provides users with technical guidelines as well as basic knowledge of common physical sensors. Piezoelectric sensors covered herein are those applied to the detection and measurement of physical quantities such as force, pressure, torque, viscosity, temperature, film thickness, acceleration, vibration, and tilt angle.

3.1.1 piezoelectric acceleration sensor element
piezoelectric sensor component whose resonance frequency or delay is used to measure the change in velocity of an object with time
3.1.2 piezoelectric humidity sensor element
piezoelectric sensor component whose resonance frequency or delay is used for dew point and moisture detection
3.1.3 piezoelectric tilt angle sensor element
piezoelectric sensor component whose resonance frequency or delay is used to measure tilt angles, elevation, or depression of an object with respect to gravity’s detection
3.1.4 piezoelectric vibration sensor element
piezoelectric sensor component whose resonance frequency or delay is used for measurement of vibration
3.1.5 dual mode sensor
piezoelectric sensor which is able to detect physical quantities from a change in resonance frequencies of two independent modes on a single piezoelectric plate
Note 1 to entry: In order to achieve improved precision and/or to eliminate undesired influence factors, sensor solutions are employed that utilize two or more modes. By evaluation of combinations of these modes’ sensitivities to various ambient conditions, on the one hand, improved detection sensitivity can be achieved, while, on the other hand, undesirable sensitivities can be reduced or eliminated.
3.1.6 differential sensor
piezoelectric sensor which is able to detect physical quantities from a change in resonance frequencies or delays of two independent and same micro-acoustic structures assembled on the same or different piezoelectric plates
3.1.7 multi-measurand sensor
piezoelectric sensor which is able to detect two or more different physical quantities from an analysis of different sensor responses
