Multi-function ultrasonic distance measuring instrument, as the name implies, is a device that can measure the distance through ultrasonic technology. It is mainly composed of transducer, transmission line, control signal, power amplifier, receiving and control circuit, and so on. It can measure the distance precisely, which is widely used in many fields.

Application Field

Ultrasonic distance measuring instrument has been widely used in industry, equipment installation, engineering measurement and some other occasions. Firstly, in industry, it facilitates the production process and makes sure the product is of high quality. Secondly, in building and construction, it helps to avoid wasting materials and reduce various construction mistakes. Thirdly, in medical field, it helps to diagnose and measure the matters in human bodies, such as heart rate, blood pressure, as well as other vital signs. Moreover, with the help of the instrument, we are able to obtain the relative positions and distances between two objects so as to ensure safety.

Working Principle

The working principle of the instrument can mainly be divided into two steps. Firstly, the transducer converts the electric signal into an ultrasonic signal by using the Piezoelectric effect. Then, this ultrasonic signal is transmitted into the air in a straight line. If it is reflected from an object, known as the echo, it will come back to the transducer. Secondly, the transducer receives the echo and convert it back to the electric signal. After comparison of the time difference between the signal response and launching, the distance is obtained.

Overall, the multi-function ultrasonic distance measuring instrument is a useful tool in many fields. Its accurate measurement and convenience make it more popular and significant nowadays.
