  • How to use a piezo transducer?

    We face various situations where we have to measure physical quantities like mechanical stress applied on metal and temperature levels in our daily life. For all these applications we need a device which could measure these unknown quantities in units and calibrations familiar to us.

  • What are the types of piezo transducers?

    There are different methods to classify the transducers that comprise but not restricted toward the function of the transducer, structure otherwise the occurrence of their working.

  • How to test piezo transducer?How to test piezo transducer?

    Piezoelectric transducers are a type of electroacoustic transducer that convert the electrical charges produced by some forms of solid materials into energy. The word "piezoelectric" literally means electricity caused by pressure.

  • What is a piezo transducer?

    Piezoelectric transducer is a sensor made of piezoelectric effect produced by certain dielectrics. The so-called piezoelectric effect refers to the phenomenon that certain dielectrics undergo deformation, including bending and stretching deformation, due to the polarization of internal charges when they are deformed by external forces in a certain direction. The most common materials used in piezoelectric transducer are various types of piezoelectric ceramics belonging to piezoelectric polycrystals and quartz crystals.

  • How to check piezo element?

    Piezoelectricity was first discovered in 1880 by Jacques and Pierre Curie. While experimenting with a variety of crystals, they discovered that applying mechanical pressure to specific piezo element like quartz released an electrical charge. It wasn’t until World War I when piezoelectric element was used for practical applications in sonar. Today, piezoelectric element is used everywhere that asking Google for directions to a new restaurant uses piezoelectric element in the microphone. However, if the piezo element does not make sound, how can we check whether piezo element is good or not?

  • How to solder piezo element?

    Piezoelectric element refers to the use of piezoelectric technology in the transducer, indicator or as an independent device to produce audible devices. Piezoelectric element is a very sensitive device, its response time is only sub millisecond, which is much shorter than the blink time. When welding pins to piezoelectric elements, great care must be taken to prevent damage to the device.

  • How many types of buzzers are there?

    The buzzer, also known as the sounder, is a miniaturized electro-acoustic device, which working principle can be divided into two types: piezoelectric buzzers and electromagnetic buzzers. Each type has specific characteristics. Generally speaking, the piezo buzzers are of higher reliability,

  • How to maintain active piezo buzzers?

    As a kind of electronic buzzer, the main energy of active piezo buzzer is provided by direct current. There are many types of buzzers, which can be classified according to current, package, structure and driving mode.

  • How does a piezo buzzer work?

    How does a piezo buzzer work?The piezo buzzer uses the piezoelectric effect of the piezo ceramics and uses the pulse current to drive the vibration of the metal plate to generate sound and is widely used as a sounding device in electronic products such as computers, home appliances,consumer electron

  • What is a passive buzzer?

    The passive piezoelectric buzzer generates sound based on the reaction of the piezoelectric effect. It is the basic principle that pressure change or strain is generated by applying an electric potential on a piezoelectric material. These passive piezo buzzers can be used to warn users of events cor
