MaxBotix Inc. develops and manufactures ultrasonic sensors in Minnesota, USA for a variety of applications. The high-performance ultrasonic distance meters are suitable for the most demanding liquid and measurement environments. The sensors are ready to use, easy to maintain and provide reliable and fast measurements for indoor and outdoor applications. The sensors are very compact and are characterised by an excellent range and low power consumption.
How an ultrasonic sensor works
Ultrasonic sensors are based on the measurement of sound waves with a frequency above the human hearing range. These in turn are based on three physical principles: Time of flight, Doppler effect and attenuation of sound waves. Ultrasonic sensors are non-intrusive as they do not require physical contact with their target and can detect certain clear or shiny targets that are hidden from view by other sensors. On the other hand, the measurements of ultrasonic sensors are very sensitive to the temperature and angle of the target.
