Presentation
The SOLIBA PM metal cage is a cast-aluminum protective enclosure designed to safeguard a SOLIBA level detector (including SOLIBA EX P ATEX versions) in bulk-handling and conveyor environments. It protects the detector from direct impacts by voluminous solid materials while allowing free movement required for reliable level detection.

Main functions
The cage prevents mechanical damage to the sensor and permits installation where abrasive or large particulate solids (stones, gravel, pellets, etc.) may strike the detector. Compatible with SOLIBA standard and SOLIBA EX P detectors certified for dust zones 21 and 22.

Detection principle
The SOLIBA detector operates by tilt: when material builds up, the bulk causes the detector to tip. The change in angle actuates an electrical contact that sends a stop or control signal to the automation (stop filling, trigger alarm, etc.).

Installation and mounting
The detector must be suspended with a free swing. Use an independent reinforcement chain to absorb mechanical shocks and avoid stress on the electrical cable. Positioning of the suspension point and ballast allows adjustment of the switching angle (greater distance between ballast and detector increases the switching angle). Maintain sufficient clearance from walls to ensure unobstructed movement.

Typical applications

• Belt conveyors
• Hoppers and silos
• Storage cells and bunkers
• High-level detection for abrasive bulk solids (stones, gravel, pellets, etc.)
