Micropilot FMR62 is the first 80GHz radar developed according to the international functional safety directive IEC 61508. For applications in aggressive liquids, FMR62 offers extraordinary advantages with its completely PTFE-filled and flush-mounted antenna. The integrated PEEK antenna allows very small process connections. The FMR62 free space radar offers maximum reliability due to improved algorithms and small beam angle. It also possesses the smart sensor functionality Heartbeat Technology.

Makers and authorised dealers rarely quote marine equipment without the vessel. With these details we can check availability and prices faster; without them we may have to ask first, which can cost a few days. If you cannot share the vessel, a photo of the equipment’s rating plate does the same job — attach it below or send it as a reply to our confirmation e-mail.
