Micropilot FMR20B - radar sensor for basic applications
Simple and efficient level measurement of liquids and solids
Advantages
Fast commissioning and operation via a guided setup sequence (wizard)
Bluetooth connection enables simple, reliable and encrypted wireless remote access
Device identification during Bluetooth connection via the “It's me-function” (LED flashing) and status indication via LED
Clear segmentation and simple configuration for easy device selection
Heartbeat Technology enables guided on-demand verification and diagnostics in the wizard without interrupting the process
Field of application
The Micropilot FMR20B uses 80 GHz technology and provides continuous non-contact level measurement. The guided wizard facilitates installation, commissioning and operation. Thanks to Heartbeat Technology, efficiency can be increased and downtime reduced through on-demand process verification and device diagnostics. The compact design of the device also allows use in confined installation conditions.
