Level switch use precautions

Note on the use of the level switch:

1. Liquidity: The material has good fluidity and is not easy to produce dead ends and bridges.

2. Dead angle: When the material level is discharged, there may be material in the lower part of the side wall that is not discharged. This area is called dead angle. Avoid the material level switch when installing

Dead end position to avoid false positives.

3. Repose angle: continuous feeding makes the material piled into a cone, and the angle between the bus bar and the bottom surface of the cone is the angle of repose. Reflects the non-adhesive surface friction. The size of the angle of repose directly affects the mounting point of the level switch.

4. Bulk density: The mass per unit volume of material directly affects the sensitivity of the level switch.

5. Bridge: When the hopper is discharging, only the material at the discharge port is released, and the upper material does not move down to form a bridge. The bridge is very harmful to the discharge and level detection.

6. The effect of powder pressure.

7. Corrosive effects.

8. The effect of moisture content.

9. Static: It may cause false alarms in the electronic circuit.

10. Particle size: The material particles are too large to easily damage the measuring rod.

11. The impact of flammability or explosiveness.
