Capacitive sensor
RFnivo® - RF 3100
Point level measurement
Solids
DK value ≥ 1,6
The capacitive point level sensor RFnivo® RF 3100 is used in storage and process vessels as a full, demand, and empty detector in all bulk solids from a DK value of 1.5. It operates at process temperatures up to +240°C and process overpressure up to 25 bar. Due to its "Active Shield" function any buildup does not in any way affect the accuracy of the measurement results of the sensor.
Simple, reliable and maintenance-free all-rounder in bulk materials
To be configured for almost any application
Plug and play level limit switch with automatic calibration
