The goal of this tutorial is to pass on the basic knowledge about piezoelectric accelerometers and related know-how. It is a practical tool for the training of newcomers in the field of piezoelectric vibration sensors.

I would like to share with you a part of my 35 years of experience in the field of vibration, piezoelectricity and accelerometers. Experience, which I have gained during my professional career in the development of control and measurement systems and especially piezoelectric sensors.

Understanding of Piezoelectric Vibration Sensors in 5 chapters

Acceleration, velocity, displacement

​The first chapter starts with a look into some basic physics of motion to allow for understanding the common vibration representations: Displacement, velocity and acceleration and their mutual dependency. To finish there is an excursion into vibration analysis:

Frequency spectrum; Fast Fourier Transform FFT.

What is electric charge? Here you will find an answer. The piezo effect is explained by a video and a step by step introduction into the function of piezo materials: Single crystals and piezo ceramics. Followed by a detailed explanation of the piezoelectric constants and a review of the most important material  characteristics.

The basic physical function and a video showing the step by step assembly procedure. Explanation of the different functional modes (compression, shear, etc.) and a few thoughts on parts design. Basics on EMI protection and signal conditioners (charge amplifier; integrated electronics piezo-electric IEPE)

Profit from this Tutorial

         by following the indicated path leading logically trough all subjects.

This course is particularly thought for persons who do not have a technical background. Nevertheless to understand the subject we will need to look in some physics. I tried my best to make the explanations as easy as possible.

You don't need to remember everything but try to work yourself along the indicated path.

There are two paths leading trough all chapters.

The  green path  (=easy path) is recommended if you are not an engineer or a technician,

while the  yellow path  presumes some basic technical knowledge.

If you don't have a distinct technical background the green path is perfect for you. It is leading logically trough all subjects and touching a basic level of understanding.

To navigate along the green path just use the green  CONTINUE   buttons.

In some places there is a yellow path going to some deeper level. If green is "cold coffee" for you then the yellow path and red pages might be more suitable for you.

Just follow the yellow  CONTINUE  buttons.

The red pages contain some more mathematical information.

Just use the   RED PAGE   button.

Under this sign              you will find additional information.
