2 Application notes Basics Ultrasonic sensors are transmitting and receiving ultrasonic signals. These signals have a frequency range from 6 khz up to 00 khz. Ultrasonic sensors can be used for several different applications, for example: diameter detection looptension height detection level measuring counting Application notes Non-contact detection of: distances presence level diameter position Independent of: material colour light smoke dust Cycle period A short ultrasonic pulse is transmitted at the time 0, reflected by an object. The sensor receives this signal and converts it to an electric signal. The next pulse can be transmitted when the echo is faded away. This time period is called cycle period. (Fig. ) Sensors with long sensing ranges have long cycle periods and slow reaction time short sensing ranges have short cycle periods and fast reaction times distance Pulse Pulse Angle of beam The energy of the ultrasonic pulse is transmitted in form of a cone along the transducer axis. The highest intensity is on the axis and decreases with rising angles. The angle of beam is defined by the angle through which the energy of the ultrasonic pulse is reduced of % of its maximum value. The best detection is given by an object that stands vertical to the transducer axis. To give a save detection, the object should not have an greater angle than half of the angle of beam ( /). (Fig. ) If the object is canted at a greater angle, there is no reflection of the ultrasonic pulses. An object with a flat surface and canted at an angle of to the transducer axis refracts the ultrasonic pulse in an angle of 90. An ultrasonic pulse can be compared to a light beam. Fig. : angle of beam Voltage amplitude During the transmission the voltage amplitude of the ultrasonic pulse is approximate 80 V PP. The pulse period of the ultrasonic pulse depends on the duration of the transmission pulse and on the ringing time of the transducer. The voltage amplitude of the received echo is in the range of V. (Fig. ) U 0 Fig. : voltage amplitude Blind zone Ultrasonic sensor Transmission pulse Acoustic beam width α Echo Transducer axis Time It is not possible to receive an echo during the transmission of the ultrasonic pulse. This time period defines the range of the blind zone. In this blind zone it is not possible to measure a distance.
