The ultrasonic distance sensor, using the principle of ultrasonic echo distance measurement, uses the precise time difference measurement technology to detect the distance between the sensor and the object. The ultrasonic sensor of small blind area developed by our factory has the advantages of accurate measurement, no contact, waterproof, anticorrosion, low cost and so on. It should be at the level of liquid.
It can ensure that there is foam or big sloshing on the surface of the liquid, and the stable output is not easy to detect when the echo is detected.
2. The way of connection:
Brown line: power - 12 or 24V
Black line: power negative
The white line: the earth
Blue line: signal output 0-5V, 0-10V, NPN, PNP
3. Application scope:

4. Product characteristics
The direct detection mode is used to get the distance signal by transmitting the time difference between the ultrasonic signal and the feedback signal, and then converted to 0-5V (0-10V, NPN, PNP) signal after the high-speed chip processing.
