Level Switch Usage and Precautions

Material flow switch fluidity: Good material flow, less prone to dead corners and bridges.

2. Blind spot: During the placement of materials at the material level, there may be materials left un-discharged in the lower part of the side wall, which is referred to as a blind spot. When installing the material level switch, avoid this area.

Dead corner positions to avoid false alarms.

3. Rest Angle: Continuous feeding causes the material to form a conical pile, with the slant height of the cone forming an angle with the base, known as the rest angle. This reflects the delicate surface friction of non-adhesive materials. The size of the rest angle directly affects the installation point of the material level switch.

4. Volume Density: The mass of material per unit volume, directly affecting the sensitivity of the level switch.

5. Bridge Formation: When the hopper feeds material, only the material at the discharge opening is released, while the upper layer material does not shift down, forming a bridge. This bridge formation poses significant hazards to the feeding process and material level detection.

6. The Impact of Powder Pressure.

7. Corrosive Effects.

8. The Impact of Moisture Content.

Static electricity may cause false alarms in electronic circuits.

10. Granularity: Material particles that are too large are prone to damaging the measuring rod.

11. The impact of combustible or explosive influences on level switches.
