Description
The RFnivo® RF-3100 Capacitive Sensor stands as a versatile, robust point-level sensor for detecting bulk solid materials across diverse industrial processes. By leveraging RF admittance measurement, it reliably distinguishes genuine product coverage from minor coating or bridging on the probe. Key advantages include:
Adaptive Shielding
Minimizing false triggers due to caking or dust.
Minimal Calibration Needs
Ready for standard solids with factory settings, plus fine-tuning if required for unusual media.
Rugged Construction
High IP enclosure, stainless steel probe, optional high-temperature or specialized coatings.
Simple Integration
Relay or transistor outputs plus fail-safe features for safe, direct interfacing with PLCs and SCADA.
Implementing the best practices will yield long-term, dependable performance in measuring powder or granular material levels. Whether preventing overfills in tall grain silos, controlling plastic pellet feed lines, or safeguarding cement mixing stations, the RFnivo RF-3100 demonstrates consistent detection that helps keep industrial operations efficient, safe, and properly informed about inventory status.
