CAMLogic Rotary Level Indicator PFG09 Series

Introduction – CAMLogic Rotary Level Indicator PFG09 Series

The CAMLogic Rotary Level Indicator PFG09 Series is a high-reliability mechanical level switch designed for monitoring granular solids in silos, bins, and hoppers. It provides precise indication of level thresholds—typically “full” or “empty”—and ensures safe and efficient operation in bulk material handling systems. Built with a die-cast aluminum housing and stainless-steel shaft, this instrument delivers long-lasting performance even in harsh industrial environments.

Thanks to its ATEX-certified explosion protection, the PFG09 Series is suitable for use in hazardous zones containing explosive dusts or gases. The IP65-rated enclosure ensures complete dust tightness and resistance to water jets, making it ideal for both indoor and outdoor installations.

Engineered for simple installation and minimal maintenance, the PFG09 requires no special tools or calibration. Its adjustable spring mechanism allows easy adaptation to materials of varying densities, while multiple paddle types offer flexibility across applications. The instrument’s excellent quality-to-price ratio makes it an efficient and cost-effective solution for level control.

Available in threaded, flanged, and high-temperature versions, the CAMLogic Rotary Level Indicator PFG09 Series meets the demanding needs of industrial automation, bulk storage, and process control sectors. Distributed by Dubai Sensor, it supports reliable operation across the UAE and MENA industrial markets.

FAQ – CAMLogic Rotary Level Indicator PFG09 Series

Q1. What is the primary function of the CAMLogic Rotary Level Indicator PFG09 Series?
A1. It is designed to monitor level thresholds—typically “full” or “empty”—in silos, bins, and hoppers containing granular or powdered materials. The rotating paddle stops when covered by material, triggering a switch signal for process control.

Q2. Can the PFG09 Series be installed in hazardous areas?
A2. Yes. The PFG09 Series is ATEX-certified for explosive dust and gas atmospheres. Models include protection for Zones 20/21 (dust) and Zones 0/1 (gas), depending on the version (PFG09, PFG09Z, or PFG09ZATF).

Q3. What materials can the PFG09 detect?
A3. It can detect bulk solids such as grains, powders, cement, plastic pellets, and other dry granular materials with densities from 0.1 to 2.0 kg/dm³. Various paddle types are available to match the material’s density and flow characteristics.

Q4. How is the sensitivity of the level indicator adjusted?
A4. Sensitivity is set using a spring adjustment inside the housing. Increasing spring tension improves performance with heavy or sticky materials; decreasing tension enhances response to light or fluffy materials.

Q5. Does the instrument require maintenance?
A5. The PFG09 Series requires no routine maintenance. Only occasional visual checks of the gasket and seals are recommended. If any parts are damaged, replacements must be sourced directly from CAMLogic or authorized service centers.

Q6. What are the power supply options for the PFG09 Series?
A6. The device can operate on 115/230 VAC, 24/48 VAC, or 24 VDC ±15%, consuming only 4 W of power.

Q7. What is the maximum process temperature and pressure rating?
A7. Standard models operate up to +70 °C and 1.1 bar pressure, while ZATF models withstand process temperatures up to +200 °C.

Q8. Can the level indicator be mounted horizontally or at an angle?
A8. Yes. The device can be installed vertically, horizontally, or obliquely, offering flexibility for different silo or hopper configurations.

Q9. What protection rating does the PFG09 have?
A9. The device is rated IP65, providing complete protection against dust ingress and resistance to low-pressure water jets, suitable for indoor or outdoor use.

Q10. Who should perform repairs or replacements?
A10. Only CAMLogic or authorized technicians should carry out repairs, following standards IEC/EN 60079-19. Unauthorized modifications void the certification and warranty.
