, most widely used in the field of industrial sensor,are made by the ultrasonic characteristics.Ultrasound is a kind of mechanical wave with a higher vibration frequency than sound wave.It is characterized by higher frenquency,shorter wavelength, less diffraction phenomenon, especially the better directivity and capacity of directional transmission.
Using piezoelectric ceramics as acoustic transmitter and receiver, Pepperl + Fuchs ultrasonic sensors make use of a kind of special material to produce recoupling layer, realizing the sound wave's decoupling in thick air. Transducers transmit sonic pulse and convert echo pulse into pressure, while built-in controllers calculate distance by acoustic velocity and the time of receiving echo. There will be a blind area which is generated by duration of sending pulse and acoustic decay time of transducers.In this area, objects cannot be detected. They are detected when entering along the horizontal direction or from the side.
-IUR2-V15 is Pepperl + Fuchs M30 series thread type ultrasonic sensor. It is characterized by temperature compensation, synchronization, changeable sensibility, current and voltage output, as well as the sensors' parameters setting by using software ULTRA300.
