Capacitive sensor
RFnivo® - RF 3300
Application area
The capacitive point level sensor RFnivo® RF 3300 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 +500°C and process overpressure up to 10 bar. Due to its “Active Shield” function any buildup does not in any way affect the accuracy of the measurement results of the sensor.
