Piezoelectric Ceramic P4 and P8 Material used in Electrical Devices
Piezoelectric ceramic Material are used to convert mechanical parameters, such as
pressure and acceleration, into electrical parameters or,
conversely, to convert electrical signals into mechanical movement
or vibration.
In sensors they make it possible to convert forces, pressures and
accelerations into electrical signals, and in sonic and ultrasonic
transducers to convert electric voltages into vibrations or
deformations.
Usually the frequency limits of applications are ascertained through the resonances involved with the transducer design and its size and shape. For a piezoceramic sheet, there is no limit for inherent frequency. A sheet of PSI-5A material which is 2.85″ square, .0075″ thick has planar dilatation mode of about 14 KHz and of 13 MHz of thickness mode vibration in the neighborhood. Limiting factors can arise such as the resistive heating of electrodes when considerable current is gathered at large surface area parts during ultrasonic frequencies.
1.What is the process of eliminating vibration through
piezoceramics?
The process of vibration cancellation can be achieved through
attaching two piezoceramic sheets to the outer surface of the
object. They should be close to the point (in a beam) where
undesired bending needs to be controlled.The first sheet is used to
measure the strain on the surface. The data from a strain sensor is
put into a smart box. This gadget controls the power amplifier
which consequently drives second sheet.As a result, the
mechanically induced movement from second sheet produces vibrations
into the structure, which counter the other vibrations.
2.Is there a possibility of Piezo technology replacing magnetic
technology anytime in the future?
The possibility of Piezo technology replacing magnetic technology
is not possible. Magnetic technology is based on force without
physical contact. On the other hand, Piezo technology is purely
derived from forces having direct contact from bodies.For instance,
Piezo actuators have the capability of making all solenoids
obsolete. However, they are heavier which is why it is highly
improbably that magnetic technology will be forgotten because of
Piezo technology.The main interest in Piezo actuators is because of
the solenoids ability to work on less power
Company introduction:
Established in 1999, Beijing Cheng-cheng Weiye Science and
Technology Co., Ltd is a professional manufacturer in ultrasonic
transducers, ultrasonic equipment and piezoelectric ceramics.
Notably in 2004, we researched and developed our ultrasonic tubular
transducer equipment into a new product that turns the extreme
inconvenience brought about by pipeline and vacuum cleaning into an
easy task. This product has been widely used in distillation, mix
and mill for various chemical procedures and has received much
praise from our customers.
