Ultrasonic Sensors

We  AnalyteControls are involved in offering utmost quality of  Ultrasonic Sensors . Ultrasonic sensors, as the name implies, use ultrasonic waves to measure distance. The sensor head sends out an ultrasonic pulse, which is reflected back to it by the target. Ultrasonic sensors use the time between emission and reception to calculate the distance to the target.

Ultrasonic sensors produce a chirp between 23 and 40 kHz, which is substantially higher than the human audible range of 20 kHz, hence the term "ultrasonic." They use this chirp to determine how long it takes for sound to bounce off an item. This is based on the same echolocation concepts that bats use to locate their prey. Because sound travels at 343 metres per second in air at normal temperature, time can easily be converted into distance, keeping in mind that the ultrasonic chirp travels both to and from the object being sensed.
