(Summary description)Piezoelectric sensors generate a voltage in the crystal by the pressure of the charge separation, which is called the piezoelectric effect. The movement of the pressure inside the crystal ions results in a form of surface charge proportional to the force and the charge is converted into a proportional voltage by a charge amplifier.

Piezoelectric sensors generate a voltage in the crystal by the pressure of the charge separation, which is called the piezoelectric effect. The movement of the pressure inside the crystal ions results in a form of surface charge proportional to the force, which is converted into a proportional voltage by a charge amplifier.
Direct measurement of the voltage is not possible because the small amount of charge generated is well insulated and the capacitance must not change. Any print can be derivative (short-circuited) and set to the zero charge of the charge amplifier, thus eliminating pressure variations and allowing direct measurement.
Piezoelectric sensors are commonly used in safety control systems and the main target area is the safety management system of the air compressor itself. There are many sensor applications in the field of safety control and as very common sensors, it is not unexpected to use pressure sensors in safety control systems.
Applications in the field of safety control are usually considered from a performance point of view, from a price point of view as well as from the point of view of practical operational safety and convenience. The choice of piezoelectric sensors has proven to be very effective. The pressure sensor uses mechanical device processing technology to mount a number of components and signal conditioners on a small chip, so that its small size is one of its advantages, in addition to its low price being another major advantage.
The accuracy of the system tests can be improved to a certain extent. In safety control systems, the pressure brought about by the compressor can be controlled to a certain extent by installing a piezoelectric sensor in the pipework at the discharge port.
This is a certain measure of protection and a very effective control system. When the compressor starts normally, if the pressure value does not reach the upper limit, the controller will open the inlet and adjust it so that the unit reaches its maximum power.
