FAQ – CAMLogic Rotary Paddle Level Switch PFG05 Series

Q1: What is the main function of the CAMLogic PFG05 Rotary Paddle Level Switch?
A1: It detects full or empty levels of granular or powdered materials in silos, bins, or hoppers. The rotating paddle stops when material reaches it, sending an electrical signal to control or monitoring systems.

Q2: Can the PFG05 Series be used in explosive dust environments?
A2: Yes. The PFG05 Series is ATEX and IECEx certified for Zones 20/21, providing safe operation in explosive dust atmospheres. A special version is also available for Zone 22 (lamp-equipped models).

Q3: What materials can the PFG05 handle?
A3: It is designed for granular and powdered solids such as cement, flour, sand, sugar, pellets, resins, or plastic granules. The paddle material can be selected to match the product’s density and abrasiveness.

Q4: What temperature ranges can this level switch handle?
A4: Depending on the model:

• PFG05ATFV: up to 200°C
  
  
• PFG05ATFHV: up to 400°C
  
  
• PFG05ATFHV60: up to 600°C
  
  

Q5: Does it require calibration or frequent maintenance?
A5: No. The PFG05 is factory-calibrated and maintenance-free, requiring only occasional visual inspection of seals and cable glands.
