Using Multiple Sensors & Avoiding Disruption To detect transparent and other items where optical technologies may fail, ultrasonic sensors are a reliable choice. For liquid level measurement, applications that use infrared sensors, for instance, struggle with this particular use case because of target translucence.įor presence detection, ultrasonic sensors detect objects regardless of the color, surface, or material (unless the material is very soft like wool, as it would absorb sound.) Ultrasonic sensors are a great solution for the detection of clear objects.
By calculating the travel time and the speed of sound, the distance can be calculated. It sends an ultrasonic pulse out at 40kHz which travels through the air and if there is an obstacle or object, it will bounce back to the sensor. The working principle of this module is simple. The sensor determines the distance to a target by measuring time lapses between the sending and receiving of the ultrasonic pulse. Our ultrasonic sensors, like many others, use a single transducer to send a pulse and to receive the echo. The transducer of the sensor acts as a microphone to receive and send the ultrasonic sound. Ultrasonic sensors work by sending out a sound wave at a frequency above the range of human hearing. High-frequency sound waves reflect from boundaries to produce distinct echo patterns.
This guide was created as an introduction to ultrasonic sensing, it’s principles, and how ultrasonic sensors work in your applications.Īt a top level, you need to know what an ultrasonic sensor is…Īn ultrasonic sensor is an instrument that measures the distance to an object using ultrasonic sound waves.Īn ultrasonic sensor uses a transducer to send and receive ultrasonic pulses that relay back information about an object’s proximity. Our technical support gets emails all of the time about how our sensors work and what environments our sensors work (or don’t work) in. I recommend it further.Ultrasonic sensing is one of the best ways to sense proximity and detect levels with high reliability.
#CALCULATION PRINCIPLES OF EASE ACOUSTIC PROGRAM SOFTWARE#
In the course of time, on the basis of my professional experience with the SoundPLAN software, I can surely state that working with such advanced software brings only benefits. Working with the program does not pose difficulties, certainly a big advantage is the possibility of temporary rental of individual modules under a given demand. In addition, the ability to export the results obtained, including isophones, allows you to freely adjust the method of data presentation to the specific requirements of the customer. While working with the program, I have not encountered a situation where an error occurred which would result in data loss, which is very important for me. The possibility of importing data from various sources and the permissible scope of their editing greatly facilitates work on a given project, significantly reduces the time of data preparation for final calculations. I have been using SoundPLAN software since 2017, initially in the essential version, but currently in the SoundPLANnoise (64-bit) version, mainly for the purposes of modeling the predicted acoustic impact of transport infrastructure investments.
