Ultrasonic Distance Sensor Selection Tips and Installation Precautions for Ultrasonic Distance Sensors

　　Ultrasonic distance sensor selection: 9 key points to keep in mind

　　1. The type of medium being measured, liquid or solid.

　　If liquid: Is there vapor, mist, foam, waves, agitation, or floating debris on the surface?

　　If solid: Is there dust?

　　2. Minimum to maximum temperature of the medium, and minimum to maximum pressure.

　　3. Corrosiveness of the medium. If installed in a tank, know the tank material and whether there is an anti-corrosion lining.

　　4. Whether explosion-proof or corrosion-proof is required.

　　5. The measurement range in meters and the required blind zone.

　　6. Working environment: e.g., open pool, covered pool, horizontal tank, vertical tank, spherical tank, and whether the tank is vented to atmosphere.

　　7. Working voltage: 24VDC.

　　8. Output signal: 4~20mA current, 485 communication output, or relay output.

　　9. Device form: integrated type.

      Ultrasonic distance sensor installation precautions

     (1) When installing the ultrasonic sensor, the emitting surface should be perpendicular to the object being measured;

     (2) Do not reverse the power line and the output signal line.
