Product Description


The principle of the piezoelectric ceramic transducer is that when pressure or tension is applied to the ceramic chip, charges of opposite polarity are generated at the two ends of the ceramic chip, and a current is generated through the circuit. This effect is called the piezoelectric effect. Therefore, in the design of ultrasonic transducers, various factors should be considered, such as acoustic impedance, frequency response, impedance matching, acoustic structure, vibration mode and conversion materials, and how to design and coordinate these factors to achieve electro-acoustic conversion. The best value. As a kind of energy transmission network, piezoelectric ceramic transducer has the problem of energy conversion efficiency.
The conversion efficiency is related to the selection of the transducer material, the form of vibration, the structure of the mechanical vibration system (including the support mechanism), and the operating frequency. Therefore, the problem of the ultrasonic transmitter is solved. There are two materials for piezoelectric ceramic transducers: magnetostrictive metals and piezoelectric ceramics. Piezoelectric ceramic transducer is an electronic ceramic material with piezoelectric characteristics. The main difference from a typical piezoelectric quartz crystal that does not contain ferroelectric components is that the main components of the crystal phase are all ferroelectric crystal grains. Ceramics are polycrystalline aggregates with randomly oriented grains, so the spontaneous polarization vector of each ferroelectric grain is also disoriented.
If a transducer made of such piezoelectric ceramics is put into water, then under the action of sound waves, charges will be induced at both ends of the transducer, which is a sound wave receiver. In addition, the piezoelectric effect is reversible. If an alternating electric field is applied to a piezoelectric ceramic sheet, the ceramic sheet will become thinner and thicker from time to time, and it will vibrate and emit sound waves. In order to make the ceramic exhibit macroscopic piezoelectric properties, the piezoelectric ceramic must be polarized in a strong DC electric field after firing, and the end face is subjected to multiple electrodes, so that the polarization vector of the original disordered orientation is preferentially oriented in the direction of the electric field, and after the electric field is eliminated , The piezoelectric ceramic after polarization treatment will maintain a certain macroscopic residual polarization strength, so that the ceramic has a certain pressure.

FAQ


  1,
Q: How to ship your products to us?
A: You are always advised the customers to choose FedEx DHL UPS TNT if your order is not so large; if your order is large, by air or by sea maybe can save a lot of shipping cost. And the shipping cost depending on the total weight of your order.
2,
Q: How about the quality?
A: In order to get a reliable quality products, please tell and list all your product quality requirements and standard your
market requested before we produce the samples for you. Usually the sample quality is agreed by both of us. So-me items have CE, FCC and RoHs Approval, but not all. Tell us if you need a special approval in your market. We prefer to supply a reliable quality products to our customers and do not compete by a lower price immolating the quality.
3.
Q: How to place an order?
A: Please send us your purchase order by email or fax. Or you can ask us to send you a Proforma invoice for your order.
We need to know the following information for your order:
A. Shipping information-company name, street address, phone number, fax number, destination airport or sea port, transportation method (by courier, by air or by ocean container)
B, Product information-model numbers, quantity, unit price
C. Delivery time required
D. Freight payment (by collect or prepay)
E. Forwarder’s contact details if there’s any in China or Hong Kong.
4.
Q: What’s your usual payment term for orders?
A: We accept terms of Bank, T/T, West union payment or Paypal.
5.
Q: How about the delivery time?
A: Usually 7-14days for a trial order or small order.
25-30days for a large order or container order. We will specify a delivery time before you order. If we meet difficulties during production and could not ship to them in time, we will inform you in advance and tell you the causes.
