Description
Application Area
The capacitance 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.
Features- Sensor suitable for high process temperatures
- Maintenance-free sensor for use in all bulk solids
- Plug and play level limit switch with automatic calibration
