Rotary Level Indicator PFG57I Series

Introduction – Rotary Level Indicator PFG57I Series

The Rotary Level Indicator PFG57I Series by CAMLogic is a compact, robust device engineered for reliable level detection in silos, bins, and hoppers—especially in plastering machines and sprayers. Designed to detect material level thresholds such as “full” or “empty,” it ensures consistent and safe operation of pneumatic and mechanical material-handling systems.

Manufactured with a die-cast aluminium housing and stainless-steel shaft, this rotary sensor withstands demanding environments, providing durability and resistance to dust and splashes. The PFG57I’s G 1½″ BSPP process connection allows straightforward installation in any orientation, supported by a counter nut and O-ring for a secure seal.

This series is designed for simple integration and minimal maintenance, operating on 24 VAC or 42 VAC with a low 4 W power draw. A built-in LED indicator and manual/automatic selector switch enhance usability and diagnostic visibility. An optional delay timer (3–10 s adjustable) ensures reliable signal output even under challenging material conditions.

Available through Dubai Sensor, the Rotary Level Indicator PFG57I Series provides a dependable solution for industrial automation and material handling across the UAE and MENA region, ensuring optimal performance and process safety in plaster applications and beyond.

FAQ – Rotary Level Indicator PFG57I Series

Q1: What is the main function of the Rotary Level Indicator PFG57I Series?
A: The PFG57I Series detects material level thresholds—typically “full” or “empty”—inside silos, hoppers, or bins, ensuring reliable operation in plastering machines and similar equipment.

Q2: Can the PFG57I be used in materials other than plaster?
A: Yes. The instrument can be adapted for other bulk materials, such as powders or granulates, by selecting a suitable paddle design for the material’s density (minimum 0.2 kg/dm³).

Q3: What power supply options are available?
A: The Rotary Level Indicator PFG57I is available in 42 VAC (standard) and 24 VAC (optional) versions, both operating at 50/60 Hz.

Q4: Does the PFG57I require regular maintenance?
A: No routine maintenance is needed. Only periodic inspection of sealing gaskets is recommended to ensure the integrity of the housing and prevent leaks.

Q5: What protection level does the device have?
A: The PFG57I Series has an IP54 protection rating, offering dust protection and resistance to water splashes.

Q6: How is the level indication shown?
A: A side-mounted LED indicates material presence — it lights up when the paddle is obstructed (material present) and turns off when the silo is empty.

Q7: Is there a delay option for the output signal?
A: Yes. The PFG57I can include an adjustable delay timer (3–10 seconds), factory-set to 5 seconds, to stabilize signal switching in fluctuating material conditions.

Q8: Can it be installed in any orientation?
A: Yes. The rotary level indicator can be installed in any position on the silo or hopper wall, thanks to its G 1½″ (BSPP) connection with supplied nut and O-ring.

Q9: What standards does the PFG57I comply with?
A: It complies with RoHS Directive 2011/65/EU and EMC Directive 2014/30/EU, ensuring environmental and electromagnetic safety compliance.

Q10: Who should perform repairs or replacements?
A: All repairs or internal servicing should be carried out only by CAMLogic or authorized technicians to maintain certification and warranty validity.
