Capacitive sensor
RFnivo®
Point level measurement
Solids
DK value ≥ 1,6
The capacitive point level sensor RFnivo® RF 3200 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 is mechanically very resilient and 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.
