Abstract
Piezoelectric sensors are used in condition monitoring system to
monitor forces, vibration, strain, acoustic emission and for other
applications.
The sensors produce a small electric charge which needs to be
amplified using a charge amplifier. Then a voltage amplifier will be
used to increase the level of the voltage to a suitable level for data
capturing using a digital acquisition system.
The task to be performed is to build and test a charge amplifier that
could be used with piezoelectric sensors re-using an old PC for the
power supply and recycle the casing of the computer for the device to
be built.
Nowadays recycling is very important when you manufacture any
product given the fact that we can get economic and environmental
benefits without affecting the product quality. Specifically in this
project an old computer which was going to be doomed, has been
used to make the casing for our device and also to feed the charge
amplifier through its power supply.
The amplifier has been manufactured by the welding of integrated
circuits. It has taken three stages of amplification which highlights
the operational amplifiers LF 356 and LF 351.
We should add that this is not a conventional project of design, but a
project mainly based on electronics and recycling. The most
important thing is the proper functioning of the device and it complies
with the requirements of the market, given that it is mostly a product
that it has been recycled and reused.
