RFnivo® - RF 8100 Capacitive Sensors

Brand: UWT GmbH
Application Area

The capacitance level detector RFnivo® RF 8100 is used in storage and process vessels as a full, demand and empty detector in all liquids from a DK value of 1.5.

It can generally be used at process temperatures up to +200 °C and process overpressure up to 35 bar.

Its "Active Shield" function ensures reliable functionality within applications with adhering material.
Features
  • Reliable measurement results even with viscous, adhesive medium due to "Active Shield" technology
  • "Inverse Frequency Shift" technology ensures precise measurement results
  • Maintenance-free sensor
