FRKA Radar Level Sensor: Precise Measurement for Liquids and Solids

The Octogon Sensors FRKA is a highly developed level sensor based on the radar principle. It uses internal electrodes that interact with the metal tank to generate capacitance values. When the volume of the medium changes, this capacitance value also changes, allowing the exact fill level to be calculated and output as an industrial standard signal. The sensor is excellently suited for measuring liquid and solid media.

Compact Design and Smart Operation

The device is housed in a robust all-metal casing. A color LCD display and user-friendly menu navigation via integrated buttons make on-site configuration particularly easy. For optimal readability, the display head can be flexibly rotated by 330°.

Reliability in Demanding Environments

Thanks to its strong anti-fouling properties, the FRKA delivers reliable results even with highly viscous media. The housing and probe are made of durable stainless steel 304, with the probe additionally coated with a protective PTFE (Teflon) layer.
