Technical Characteristics and Mechanical Strength
-
High Lateral Load Resistance: Unlike standard level probes, the FTI55 is built to endure the significant side-forces (up to 300 Nm) exerted by heavy, moving bulk materials during filling or discharging cycles.
-
Active Build-up Compensation: The probe is designed to maintain switching accuracy even when covered in dust or sticky residues. It distinguishes between a “covered” probe caused by a full silo and mere material caking on the rod, ensuring maximum process reliability.
-
Durable Insulation: Available in both fully and partly insulated versions, the rod is protected against abrasive materials and chemical influences. For partial insulation models, the rod can be easily shortened on-site to match the exact requirements of the measuring point.
-
Static Discharge Protection: To prevent damage from the high static charges often generated in dry solids silos, the FTI55 includes a two-stage overvoltage protection system.
-
Continuous Self-Monitoring: The device features permanent automatic monitoring of the electronics. Any malfunction is detected immediately, increasing the overall safety and availability of the plant.
-
Simple Commissioning: Set-up is fast and user-friendly, with calibration performed at the press of a button, eliminating the need for complex manual adjustments.

주요 응용 분야
-
Heavy Industrial Silos: High or low level detection for cement, gravel, sand, and ore where mechanical impact is frequent.
-
Food and Agriculture: Level monitoring in grain elevators and silos for flour or animal feed.
-
Chemical Powders: Handling fine-grained powders that may be prone to static charge or dust explosions.
-
Logistical Optimization: When combined with Fieldgate technology, it supports inventory control and supply chain management by providing reliable “reorder” signals.
-
High Lateral Load Zones: Ideal for installation near the filling stream or in silos where material “bridging” and collapse can create sudden side-forces.
