Piezoelectric Ultrasonic SensorsThis Piezoelectric ultrasonic sensor radiates the ultrasonic in the air, and receives the reflection wave from the object, and measures the presence of the object or the distance to the object. Because the ultrasonic wave reflects to a transparent object, it is possible to use even by the one that it is not possible to detect by optical. A passive method and an active method will offer both wide usage sensorsFeature for ultrasonic sensors:High pitched sound pressure and high sensitivity.
Small size, lightness in weight, and solidity.
High accuracy and high reliability.
Low power consumption and economical efficiency.
Environmental withstanding for tepid, humidity and
dirt.
