Description
Welcome to buy our ultrasonic transducer piezoelectric rectangular plate. Its length is 20mm and width is 10mm. And sheet thickness is 1mm. Therefore, this cheap price piezo sheet frequency is 2MHz. It prints the standard silver electrode. That is, the positive and negative electrodes are on two sides of the pzt ceramic plate. If you need the plates with wires, we can solder them.
Rectangle piezoelectric sheet has wide applications. For example, we can apply the pzt sheet to make vibration sensors and pressure sensors. In addition, rectangular piezo ceramic plates are suitable for acoustic devices. Hydroacoustic transducers often need them. And they can also act as the energy harvesting plates.

How to calculate the voltage of this piezo electric ceramic plate?
When apply some force on pzt plates, the phenomenon of electric charge accumulation will occur. But how many voltages it will generate? First of all, we need to know the calculation formula. That is, plate voltage = V = (g33*F3*h)/(l*w). Here we assume that the force acting on the rectangular piezo plate is 30N.
Kind notes:
The plate vibration mode is in the thickness direction;
g33: Piezoelectric constant in ‘10^-3 Vm/N’;
F3: Force in ‘N’;
h: height (thickness) in ‘mm’;
l: Length (length) in ‘mm’;
w: Width in ‘mm’;
According to material performance sheet, we know g33 value of PZT-5H is 23.9 (10^-3 Vm/N). So it can calculate voltage of piezoelectric rectangular plate now. V=(g33*F3*h)/(l*w)=[23.9 (10^-3 Vm/N)*30N*1mm]/(20mm*10mm) = [23.9 (10^-3 V*1000mm/N)*30N*1mm]/(20mm*10mm) = 3.585V.
Therefore, it can generate 3.585V voltage when applying 30N force onto rectangle piezo sheet.
The advantages of our rectangular plate ceramic plate:
Firstly, our piezo sheet has cheap price and stable performance;
Secondly, our pzt ceramics have a high electro-mechanical conversion efficiency: they can efficiently convert mechanical energy into electrical energy and vice versa.
In addition, our rectangle piezoelectric plates have a long service life. Not easy to age or fail. So it can maintain good performance for long time.
Finally, we offer custom services:
① Provide multiple electrode types;
② Solder wires to rectangular piezoelectric ceramic plates;
③ Customize the performance of pzt sheets according to the needs of customers;
Industry applications of rectangular piezo ceramic sheets:
We apply pressure or tension to the pzt plate. At this time, it will generate a voltage difference between the two ends of the ceramic. Conversely, we can also apply a voltage to both ends of pzt sheet. Then it will produce deformation. This unique property makes rectangular piezoelectric plates widely used in the fields of sensors, actuators, and energy conversion.
① Sensor technology: Rectangular piezoelectric ceramics play an important role in sensor technology. For example, in pressure sensors we measure the voltage difference generated by the piezoelectric ceramics. It can detect the amount of pressure precisely. In addition, we can also use it in acceleration sensors, acoustic wave sensors, and so on.
② Precision positioning and control System: rectangular pzt plates have the features of fast response and high precision. Therefore, it is widely applicable in precision positioning and control systems. For instance, in the field of optical instruments, precision machinery and aerospace, piezoelectric ceramic sheets play a key role.
③ Vibration sensors: we can use their piezoelectric effect to detect the vibration state of objects. They can detect small changes in vibration. So it has wide applications in machinery fault diagnosis, structural health monitoring and seismic monitoring and other fields.
④ Acoustic devices: rectangular piezo sheets can be made into ceramic speakers. So we can use them for acoustic signal processing and communication.
⑤ Medical imaging: they can convert electrical energy into mechanical energy for ultrasonic transmission and reception. Therefore, piezoelectric rectangular plates are suitable for ultrasonic diagnosis and treatment.
