2 Types and 3 Common Uses of an Ultrasonic Sensor


Industrial firms worldwide use ultrasonic sensors in a range of applications. An ultrasonic sensor employs high-frequency sound waves to resonate at a specific frequency. It converts electrical energy to acoustic energy.

2 Types of Ultrasonic Sensors

Ultrasonic sensors have two variations that have very different purposes. They are:

#1 Proximity Sensors

Many manufacturers include this in their vehicles since vision sensor systems can be expensive. It tracks an item moving through the predefined range and generates an output signal. The detection point of the sensor is unaffected by the size, substance, or reflectivity of the target.

#2 Ranging Sensors

It works in the same principle as a capacitive proximity sensor. The time intervals between transmitted and reflected bursts of ultrasonic sound estimate the precise distance of an item moving to and from the sensor. The distance change is computed and outputted in real-time.

3 Common Applications of Ultrasonic Sensors

As stated above, there are many industrial applications for an ultrasonic sensor worldwide. The following are three of the most common areas of application.

#1 Tank Level

Liquid level sensors are essential for process control and inventory management. It also ensures the prevention of wastage. It works on the same premise as a capacitive sensor.

#2 Production Line

An ultrasonic sensor may be used in the production process to automate process control on the factory floor. The sensors are essential tools for businesses to increase productivity by taking accurate measurements and control. Ultrasonic sensors can help to speed up production.

#3 Distance Measurement

An ultrasonic sensor can detect the distance between various objects, independent of their form, colour, or texture. The sensor may also determine if an item is coming or retreating.
