What is an Ultrasonic Sensor?

What is an Ultrasonic Sensor?

What is an ultrasonic sensor? An ultrasonic sensor is a type of position sensor; they detect the position, displacement or shape of an object using ultrasonic sensing technology.

They are completely non-contacting which makes them suitable for different applications than contacting position sensors.

Ultrasonic Sensors detect position by emitting soundwaves, the sound waves bounce off of objects and are reflected back to the sensor itself. The sensor can determine the position of the object based on the intensity of the received signals.

Ultrasonic sensors can also be used for proximity detection – they will monitor a specified area and will alert the user when an object enters that area irrespective of its size or shape.

What is an Ultrasonic Sensor Used for?

An ultrasonic sensor is essentially used to monitor position and detect movement. They are used for this purpose throughout many industries. As they are non-contacting, they are particularly well suited to applications in the food and beverage industry, such as bottle filling and other automated processes.  Some specific applications are;

·         Stacking and height control

·         Liquid level detection and control

·         Counting people and people detection

·         Detecting breaks in wires or threads

·         Irregular parts detection

·         Tank level detection

·         Distance detection

·         Box sorting

·         Robotics sensing

·         High speed counting of objects

·         Barriers in car parks

·         Car wash systems

These are just a few examples of what an ultrasonic sensor can be used for.

Advantages of using Ultrasonic Sensors

Ultrasonic sensors are non-contacting which contributes to the advantages they have;

Wear Free – Ultrasonic sensors are completely wear free, they have no moving parts.

Highly accurate – Ultrasonic sensors can even detect the thickness of an object as well as the depth of the parallel surface.

Shape Detection – other types of position sensor are limited to detecting the position of an object whereas an ultrasonic sensor can also detect the size and shape of the object in question.

Easy to Use – ultrasonic sensors are easy to use; they easily interface with a microcontroller and they are not dangerous to operate.

Ultrasonic Sensors from Ixthus

Our range of ultrasonic Sensors come from our supplier Migatron, they are made with piezoelectric crystals and use high-frequency sound waves to detect the position of objects.

Migatron have different ranges of sensors suitable for different environments, these include; highly accurate range, self-contained sensors, close-range sensors and intrinsically safe sensors.

As well as the advantages listed above, Migatron ultrasonic sensors also have the following advantages

·         Ability to measure and detect distances of moving objects

·         Impervious to target surface or colour

·         Ability to detect small objects even over long distances

·         Resistant to environmental variables.

·         High accuracy
