Capacitive sensor
RFnivo® - RF 8200
Point level measurement, Interface level measurement
Liquids
The capacitive level detector RFnivo® RF 8200 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 +400 °C and process overpressure up to 35 bar. Its "Active Shield" function ensures reliable functionality of the sensor against any buildup.
Reliable measurement results even with viscous, adhesive medium due to "Active Shield" technology
"Inverse Frequency Shift" technology ensures precise measurement results
High-quality graphite and ceramic materials guarantee maintenance-free operation even at high temperatures
