FAQ – CAMLogic Rotary Blade Level Indicator PFG57AT Series

Q1. What is the main function of the CAMLogic PFG57AT Series?
The PFG57AT Series is a rotary blade (paddle) level indicator designed to detect material presence (full or empty point) in silos, hoppers, and bins containing granular or powdered solids.

Q2. In what environments can the PFG57AT be used?
It is certified for ATEX and IECEx Zone 20/21 explosive dust atmospheres, with the optional lamp version suitable for Zone 22 applications. It also performs reliably in non-hazardous industrial environments.

Q3. What temperature ranges does the PFG57AT handle?
The standard model operates from –20 °C to +200 °C, while the low-temperature option (PFG57…/B) functions down to –40 °C. Special ATFV configurations (PFG05 models) can reach up to +600 °C.

Q4. What materials is the housing made of?
The housing is built from die-cast aluminium, while the shaft and paddles are made from AISI stainless steel, ensuring corrosion resistance and mechanical strength.

Q5. Does the device require maintenance?
Routine maintenance is generally not required. Only periodic checks of seals, gaskets, and cable glands are recommended. Any repairs should be performed only by CAMLogic or under its guidance.

Q6. Can the PFG57AT be installed in any position?
Yes. It can be installed vertically, horizontally, or at an angle. For horizontal installations, orient the cable entry downward or to the right, depending on the model.

Q7. What power supply options are available?
The unit supports 115/230 VAC, 24/48 VAC, and 24 VDC ±15% power supplies, consuming approximately 4 W (11 W for the low-temperature version).

Q8. How does the PFG57AT detect material presence?
When the paddle encounters material, it stops rotating. The built-in SPDT switch then changes state, sending a signal to indicate “full” or “empty,” depending on wiring configuration.

Q9. What protection rating does it have?
It is rated IP65, meaning it is dust-tight and protected against water jets — ideal for both indoor and outdoor use.

Q10. Where can I purchase or get technical support for this product?
The CAMLogic Rotary Blade Level Indicator PFG57AT Series is available through Dubai Sensor, the authorized distributor for the UAE and MENA region.
