What are the Applications of Ultrasonic Sensors and Transducers?

Ultrasonic transducers are very important in the detection of leakages and gauging the thickness of various equipment which is essential in the process industries. Transducers and ultrasonic sensors are used in very many fields like medicine, process industry and in the areas of electronics due to the many benefits they have in those fields. Transducers usually form the basis of the ultrasonic system and come in different models, sizes, and specifications to meet the needs of any customer in the detection of flaws and measuring of the thickness of materials. Scientists have defined a transducer as a device which transforms one form of energy into the other. This article tends to give the significant areas where ultrasonic sensors and transducers are applied.

You need ultrasonic sensors and transducers to enable you to measure the level of any substance in process equipment. The measurement of the concentration of different things has a lot of applications in the technological era we are living in today. The nature of the substance is not so much critical since ultrasonic sensors will measure its level regardless of its kind. Liquids which include milk, paint, chemical elements, acid and other bulky slurries their level in the process equipment can be successfully measured by ultrasonic sensors. Ultrasonic sensors will control the level of various substances in the process equipment. These sensors are therefore very essential in almost all types of chemical industries which manufacture fluid elements. Visit page for more details about ultrasonic sensors.

You also need ultrasonic sensors to detect the Boom height on Agricultural equipment. Ultrasonic sensors have been found to have varied applications in agriculture and in particular the material which are used in agricultural practices. For instance, ultrasonic sensors are commonly used in monitoring then height of spraying machine to ensure regular spraying over a garden which looks uneven and protect the plants from being affected by the boom. Ultrasonic sensors can detect any colors in different places and defense against various substances such as dust and toxic chemicals.

You also need to use ultrasonic sensor devices in spraying nozzles. Spraying is a significant activity in agriculture and primarily to prevent crops from pests which usually cause harm to them. Spraying can also be used in cattle to remove and avoid parasites which are a great nuisance on the health of the animal in question. Spraying is, therefore, a significant activity for any farmer who wishes to increase his or her yields. To improve on returns and cut on costs of spraying, farmers should be very creative. It's therefore critical for farmers to use ultrasonic detectors which save on the use of the pesticide since it can detect the gaps between crops. The moment the difference is sensed, the spraying process automatically subsides.

All You Need to Know concerning Ultrasonic Sensors and Transducers

Actually, Ultrasonic Transducers and Sensors are basically a set of acoustic sensors that are made up of a transmitter, a receiver, and a trans-receiver device. The transmitters are responsible for the conversion of signals mostly sound and electrical into ultrasound signals and sending them to the receiver. Here these signals are converted back to electrical signals.

These devices work in more or less the same manner as a sonar or a radar when it comes to sensing and interpretation of movements and sound waves. Ultrasound sensors and transducers are commonly used to measure speed, strength and direction of the wind, detection of speed and movement from secured and restricted areas, channel and fluid tank levels as well as measurement of tide characteristics.

They are also used in industrial application where they are used to monitor and control devices using sound ranges that are far beyond normal human being hearing such as twenty thousand Hz or higher. They are also used to monitor and calculate the distance of a certain target object. This system works through vibrations.

When the ceramic transducer vibrates, these vibrations are compressed, expanded and transmitted towards the target object by the transducer. The sensor then measures the distance covered by the sound to reach the object and the time taken by the echo sound to return. Through this, the distance and direction of the target object are identified.

Due to the fact that these devices use sound instead of light to detect objects, they are ideal for areas where photoelectric sensors cannot be used. They are also ideal for a section of objects in areas that have high glare characteristics. However, when you are looking for an Ultrasound Transducer or Sensor, there are some aspects you need to consider. These aspects include.

1. Sensing Distance.

It is obvious that these devices are bought in order to offer detection services. You will need to understand the maximum distance that your ultrasonic transducer and sensor can detect. In order to understand a quality sensor, you need to make sure the device has the ability to detect objects a certain distance beyond the maximum distance.

2. Blanking distance.

Blanking distance basically means the area from where the device is located and the first few feet or inches that the device cannot be able to detect an object. Therefore, you need to understand that if the device detects objects from very far distances, the same way its blanking distance is long. Due to this fact, you need to make sure that the device is able to cover both short and long range distances effectively.

Ultrasonic Sensors: Why Range is Attached to Frequency

Ultrasonic sensors can be very interesting. Sound waves are sent and received by transducers, the sensor automatically shows measurements, and it all happens without human intervention. You can select sensors according to range transducer type or even reviews or ratings. Sensors usually reflect their range and frequency simultaneously, which is somehow intriguing.

So why is an ultrasonic sensor's range always attached to its frequency? First off,
ultrasonic sensors utilize ultrasonic waves when measuring distance. The whole wisdom behind ultrasonic sensors is that distance is equal to time multiplied by velocity. For a certain combination of air temperature, humidity and other atmospheric conditions, sound velocity is known. Therefore, the time it takes for a sound wave to move from the transducer's sensor to its destination and back, must have a lot to do with the distance between them. But of course, that was clear from the start. For more information about ultrasonic sensors view here.

The question is, why are effective detection ranges shorter when it comes to higher frequency sensors?

When you talk about signal loss of any kind, attenuation is always to be blamed. This certainly applies to sound waves. Sound waves travel through the air (and everything else), which means air properties resisting that motion accumulate together. This is known as attenuation. As earlier mentioned, the speed of sound is influenced by atmospheric conditions, making them a substantial part of sound attenuation in air.

For sound waves between 50 kHz and 300 kHz, maximum attenuation can be estimated at ?(f) = 0.022 * f - 0.61, where ?(f) refers to the maximum attenuation in dB/ft, while f is the sound wave's kHz frequency. This equation may not seem to shed light on anything. After all, a factor of 0.022 is quite tiny. Attenuation is 0.5 dB/ft at 50 kHz, but it magically soars to 2.7 dB/ft at 150 kHz. Obviously, the decline in signal is not gradual, but sharp and abrupt.

Even then, that's not all there is to it. The above equation is only applicable to the full humidity range and leaves out changes in atmospheric pressure, although the effects are not very significant. Still, you have to note that the equation measures dB for every foot lost, but it is clueless as to the sensitivity of your sensor or the strength of your signal.

Hence, it is important to keep in mind that not all ultrasonic sensors are the same. Some are as basic as having little to zero configurable options, while others give you full control. At the end of the day, you still have to look for the sensor that is best aligned with your needs. Frequency is, without doubt, a big part of the picture, but it's still not everything.
