CAMLogic Rotary Level Indicator PFG57 Series

Introduction – CAMLogic Rotary Level Indicator PFG57 Series

The CAMLogic Rotary Level Indicator PFG57 Series is a high-performance solution for monitoring and controlling solid material levels in silos, bins, and process tanks. Designed for reliability and safety, this device detects level thresholds — typically “full” or “empty” — in granular and powdered materials. Its robust die-cast aluminium construction and compact form make it suitable for confined installations, including small tanks and load cells.

Built in accordance with the latest ATEX and IECEx standards, the PFG57 Series ensures safe operation in areas where explosive dust or powders are present. It features a stainless-steel shaft, modular paddle design, and IP65 protection, ensuring durability even in harsh industrial conditions.

With easy installation and versatile mounting options (threaded or flanged), this rotary level indicator requires no special tools or adjustments. The availability of multiple paddles and extensions allows precise adaptation to a wide range of bulk material densities, from fine powders to coarse solids.

Supported by Dubai Sensor, the PFG57 Series provides a reliable, certified level detection solution trusted across industrial automation and process control sectors in the UAE and MENA region.

FAQ – CAMLogic Rotary Level Indicator PFG57 Series

Q1. What is the primary function of the CAMLogic PFG57 Series rotary level indicator?
A1. The PFG57 Series detects the presence or absence of bulk solids — such as powders or granules — at a specific level (full or empty) inside silos, hoppers, or tanks. When the rotating paddle contacts material, it stops, activating a switching signal to control the process.

Q2. In what types of materials can the PFG57 Series be used?
A2. It is suitable for a wide range of bulk materials, including powders, grains, cement, sand, plastic pellets, and other granular or powdered solids. Different paddles (AISI 304) are available for various material densities.
