Ⅰ、Overview of ultrasonic position sensor
Ultrasonic displacement sensor is a kind of mechanical wave whose vibration frequency is higher than that of sound wave. It is developed by using the characteristics of ultrasonic wave and vibrated by energy exchange wafer under the excitation of voltage. It has the characteristics of high frequency, short wavelength, small diffraction phenomenon, especially good directivity, can become a ray and directional propagation.
Ultrasonic displacement sensor ranging generally uses TOF (Time of Flight). Distance between ultrasonic displacement sensor and obstacle S=vt/2. According to the principle of time of flight between ultrasonic transmission and reception, the acoustic medium is used for non-contact non-wear detection of the detected objects, transparent or non-ferrous objects, metal or non-metallic objects, solid, liquid, powder substances can be detected. Its detection performance is not affected by workpiece color, material, transparency, including dust environment and rainy days. Can be widely used in level (liquid level) monitoring, robot collision prevention, all kinds of ultrasonic proximity switches, as well as anti-theft alarm and other related fields, reliable work, easy installation, waterproof type, launch Angle is small, high sensitivity, convenient and industrial display instrument connection.
Ⅱ、Ultrasonic position sensor application field
Distance measurement, level measurement, height measurement, interval measurement, size measurement, material accumulation height measurement, filling level measurement, filling liquid level detection, diameter and velocity measurement, contour measurement, tension control, packaging detection, object counting, etc.

Ⅳ、Installation instructions
Due to the directional nature of ultrasonic sensor, it is necessary to pay attention to its installation position. It is recommended to install the best position and the object to be measured vertical, so that the measurement data will be relatively accurate. (with mounting retaining nut).
Ⅴ、Matters needing attention
● The sensor is a precision instrument, do not scratch the surface.
● Do not use this sensor in vacuum or explosion-proof area.
● Ensure that the supply voltage and ripple voltage of the sensor are within the specification range.
● Do not use this sensor near water, steam, acid or solvent above 50℃.
● When the sensor is used, there should be no strong mechanical vibration, and the working environment should not have strong electromagnetic interference.
