Ultrasonic sensors measure the distance from the sensor to an object via air without making physical contact. They calculate distance by emitting high frequency soundwaves (also known as ultrasonic soundwaves) towards the object being measured.
By receiving the reflected soundwave and calculating the time between emission from the source and reception back at the source, distance can be measured.
Ultrasonic distance measurement sensors can be used in a broad range of scientific and industrial applications where the non-intrusive capabilities of a measurement device are crucial.
Ultrasonic sensors are manufactured in a wide range of variants and specifications to adhere to differing measurement criteria and restrictions. This increases the likelihood, but also the potential complexity, of a customer finding a sensor that is appropriate for their unique application.
