Ultrasound Equipment Using Piezo Ceramics Heat Resistance and Good Quality

 

 

 

Piezoelectric ceramic materials are electromechanical transducers: They can convert mechanical energy into electrical energy and vice-versa.  Piezoelectric ceramic material from us are used in sensors, actuators, gas ignition and in power transducers for high-power ultrasonic applications.

 

 

 

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.

APPLICATION ANSWER

1.The frequency limit of apiezoceramic sheet and some properties?

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.

2.Is there any truth to piezo transducers being used as static and dynamic force sensors?

Due to charge leakage the Piezo transducers cannot be used for static force measurements. For transient force measurements they can be applied successfully for only0.1 second.

 

3.The expected life of piezoelectric material?

There are no tests yet that can determine the “fatigue life”. Our facility has had an operational piezo fan since 1982. Such calculations must involve voltages and mounting.

 

4.How does temperature effectpiezoceramic transducers?

The pyroelectric properties of piezoceramic are responsible for the appearance of voltage through the any piezo transducer electrodes due to temperature changes. Almost each and every property of piezoceramics is affected by temperature. There exists no general manner regarding it. In accordance to your experiment and calculations, the dependence must be looked upon in that context.

PIEZO TECHNOLOGY ANSWERS

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 powe
