Rotary paddle level switch for monitoring a level threshold, generally full or empty. For solid materials in silos or bins. Sturdy construction with aluminium casing. Guaranteed reliability at an excellent quality price ratio. The ideal sensor for heavy-duty conditions and continuous cycles, even in atmospheres that are potentially explosive owing to the presence of dusts/powders. Conforms to the most recent ATEX standards.



  • Version for high temperatures up to 200°C and for contact with corrosive
  • Easy to install: specific tools or settings are not required.
  • Provides the highest standard of safety in the presence of potentially explosive dusts/powders.
  • Probe can be adapted to the material with a broad range of plastic or stainless steel paddles.
  • Mechanical and electrical customizing of the measuring instrument on request.
  • Extremely reliable, the instrument can be used in addition to radar sensors, capacitive, ultrasound or continuous level probes as a safe signal

Electrical specifications

The electrical part of the entire range of PFG05 level probes can be supplied with different voltage ratings and numerous optionals.

  • Available voltage ratings: 115/230V or 24/48V – 50 … 60Hz (AC) and 24V (DC).
  • Standard version with faston connectors.
    Paddle terminals or self-locking spring terminals are available on request.
  • Voltage monitoring: to remotely check that the indicator is energized correctly.
  • Double contact: additional potential-free contact for monitoring the automatic parts of the system.
  • Rotation control: enables indicator operation to be monitored remotely.
  • 4 RPM: increased rotation speed to reduce trip time.
  • Low temperatures: enable the instrument to function down to -27°C.
