Piezoelectric-Ultrasonic-SensorsPiezoelectric ultrasonic sensors

The ultrasonic sensors send ultrasonic wave to the air, and detect the ultrasonic echo from the impediment. The ultrasonic sensors are multipurpose, for example, it used as Burglar alarms, Range finders, Automatic doorsBack sonar of automobiles, Parking meters,Water level meters and so on. With the information technology developing rapidly, the areas of new ultrasonic sensors applying for automatic equipments in factories and electrical devices in cars, are increasing day by day, and will go on.
Resorting to the advanced technology and perennial experience, our company have researched and developed manifold types Ultrasonic sensor which has ascendant performance just as such the compact and light weight, the high sensitivity and sound pressure, the less power consumption and high reliability. The information in this presentation is very helpful for you to effectively use our ultrasonic sensors.
Application theory:The piezoelectric effect describes the relation between a mechanical stress and an electrical voltage in solids. It is reversible: an applied mechanical stress wil generate a voltage and an applied voltage will change the shape of the solid by a small amount (up to a 4% change in volume). In physics, the piezoelectric effect can be described as the link between electrostatics and mechanics. The Ultrasonic sensor application theory When an AC voltage drivers the piezoelectric ceramic, it mechanically vibrates with a certain frequency. The opposition is true, when the ceramic vibrates, it will produce an AC voltage. This is the piezoelectric effect. Using this theory , when sending an electric signal, the oscillator that consists on the two sides of the piezoceramics can bends and sends ultrasonic waves. Basing on the effect, we wil use the piezoceramics in the ultrasonic sensors.

Open Structure Ultrasonic sensor

As the figure of ultrasonic sensor, a compound oscillator is fixed on the base flexibly. The compound oscillator is a conjunct object that is made from cone, piezoceramics and a metal plate. The oscillate looks as a loudspeaker, it can radiate ultrasonic wave that the compound oscillator vibrates to produce effectively, and can get ultrasonic wave in the center of the oscillator together effectively. The follow is the sketch map Of Open StructureUltrasonic sensor.
Open Structure Ultrasonic sensor Features:
1. compact and light weight
2. high sensitivity and sound pressure
3. less power consumption
4. high reliability
Application: Burglar alarms, Range finders, Automatic doors and so on

 

Water Proof Type Ultrasonic Sensor
Structure of Ultrasonic Sensor The Ultrasonic sensor using outside must be better sealed, so that prevent dew, rain and dust from the outside. The piezoelectric ceramic is fixed inside of the top of a metal box. The base is fixed in the hatch of the metal box, and cover with the resin. The right sketch map is the water proof structure ultrasonic sensor. Water proof Ultrasonic Sensor.
Features:
1. compact and light weight
2. high sensitivity and sound pressure
3. less power consumption
4. high reliability
5.Compressed directivity by itself
Application: Back sonar of automobiles,Parking meters,Parking sensor,Water level meters and so on.
