RFnivo® - RF 3200 Capacitive Sensors

Brand: UWT GmbH

The RFnivo® RF-3200 is a capacitance-based RF admittance level sensor engineered for robust and accurate point-level detection in bulk solids and certain liquid or slurry contexts. By harnessing guard or shield technology, it differentiates between genuine coverage and incidental buildup on the probe’s upper portion, minimizing false triggers and ensuring stable switching for a range of applications—from grains and plastics to chemical powders and beyond.

Mechanical Simplicity
A single rod with advanced electronics, no external moving parts to wear out.

Coating Compensation
Active guard design neutralizes mild buildup, preventing spurious coverage signals.

Minimal Calibration
Typically arrives set for standard solids; minor tweaks may handle borderline dielectric or bridging scenarios.

Versatile Mounting
Threaded or flanged connections, plus optional high-temp or extended rods for deep vessels, adapt easily to various process setups.

Safe Integration: Industry-standard outputs (relay, transistor, two-wire) link directly with PLCs or SCADA, offering fail-safe modes to maintain safety if the sensor loses power.

Facility managers can benefit from long-lasting, precise point-level detection. This leads to smoother material handling, fewer unexpected line stoppages, reduced spillage risks, and overall better operational efficiency in industrial environments.

Features
  • Mechanically very resilient
  • Maintenance-free sensor for use in all bulk solids
  • Plug and play level limit switch with automatic calibration
