CAMLogic Rotary Paddle Level Switch PFG05 Series

Introduction – CAMLogic Rotary Paddle Level Switch PFG05 Series

The CAMLogic Rotary Paddle Level Switch PFG05 Series is a robust and reliable instrument designed for level detection of granular and powdered bulk solids in silos, hoppers, and bins. It provides accurate point-level monitoring for both full and empty conditions, ensuring efficient and safe process control. Built with a die-cast aluminium housing and AISI 303 stainless steel shaft, this device withstands the harsh conditions of industrial environments while maintaining consistent performance.

With a rotation speed of 1 rpm, the paddle continuously monitors the presence of material—triggering a signal when resistance is detected. Thanks to its mechanical reliability, the PFG05 Series can serve as a dependable alternative to radar, capacitive, or ultrasonic sensors in challenging solid-handling applications.

Complying with the latest ATEX and IECEx standards, this rotary paddle switch guarantees safety in dust-explosive atmospheres (Zones 20, 21, and 22). It is available in several configurations with customizable paddles, power supply options, and electrical outputs to suit a wide range of materials and operating conditions.

Engineered and manufactured in Italy, the PFG05 Series is distributed in the UAE and MENA region through Dubai Sensor, providing industries with a durable and cost-effective solution for bulk material level control.
