Product line: Rotary Bladed
Materials: Solids - High temperature - Corrosive

Rotary blade level indicator used for detecting a level threshold, generally full or empty, in a silo or bin. Sturdily built thanks to its aluminium casing and small in size, it is ideal for installation in small tanks or load cells and, in accordance with the most recent ATEX standards, for use where the atmosphere is potentially explosive owing to the presence of dusts/powders.

 

Advantages

  • Version for high temperatures up to 200°C and for contact with corrosive
  • Easy to install:specific tools or settings are not required.
  • Extremely versatile and with an excellent quality price ratio.
  • Provides the highest standard of safety in the presence of potentially explosive dusts/powders.
  • Probe can be adapted to the material monitored thanks to the wide range of paddles available.
  • Extremely reliable, the instrument can be used in addition to radar, capacitive, ultrasound or continuous level probes as a safe signal.

  • Standard version with faston connectors.
    Paddle terminals or self-locking spring terminals are available on request.
  • 4 RPM: increased rotation speed to reduce trip time.
  • Low temperatures: enable the instrument to function down to -27°C.

Choice of paddle

An essential component that ensures the level indicator functions correctly, the paddle is the basis from which customizing starts since it can be adapted to every type of use.
To make the best choice, it is important to bear in mind the following 5 key points:

 

  1. Each material has a minimum density that must be detected by the instrument.
  2. The minimum diameter of the entry hole through which the paddle can pass if it cannot be installed inside.
  3. The diameter occupied by the paddle as it turns.
  4. The number of blades changes depending on the intensity of the disturbances to which the paddle is exposed.
  5. Polyamide or stainless steel, depending on the type of material with which the paddle comes into contact.
