Ultrasonic distance measurement is a “Non Contact” method of measurement of distance in air of an object. Ultrasonic Distance measurement provides a reliable, accurate and fast way to measure distance and calculates the area & Volume of any space. An ideal tool for Architects and Civil, Survey Engineers.
Working Principle :
Principle used is known as “Pulse - Echo” technique. An electrical pulse of high voltage is applied to the ultrasonic transducer to generate a burst of sound waves. Whenever, any obstacle is encountered in the ultrasonic path, the pulse is reflected back in the form of an echo. It calculates the time taken between Transmitting signal and receiving echo and with input of Velocity of Sound in air, distance is displayed on the Instrument.
