Ultrasonic sensors are used for automated process control.
By detecting an object, the sensor can trigger certain steps in the production process. For example, high-speed counting and sorting of boxes and other operations due to the high update rate.
By detecting translucent objects such as water, the sensor can measure the level of the liquid. For this scenario, it can be mounted above the tank. By sending beeps, the sensor will detect the level of liquid in the tank and measure the return time of the beep. The lower the liquid level, the longer it will take for the signal to return to the sensor and vice versa, giving the operator real-time data on the liquid level.
Ultrasonic transducers can be purchased either as independent transmitters and receivers or as a combination of the two devices in a single unit called an ultrasonic transceiver. The selection of the appropriate beam angle emanating from the transducer depends on the purpose of the system. Wide beam angles are suitable for detecting objects where perhaps less accuracy is required, while narrow beam angles avoid false alarms at longer distances. You should also consider whether to choose a standard or high-frequency sensor, and whether the intended work environment may benefit from an IP-rated sensor.
The diverse applications of ultrasonic sensors are attributed to their simple operating principle, reliability, and cost-effectiveness in various designs. As the IoT market grows, ultrasonic sensors will continue to be in demand, for detecting and monitoring objects.
