Endress+Hauser Micropilot FMR67B 80GHz Radar Level Transmitter | Non-Contact Solids Level Measurement for High Silos & High Temperature

Applications

Micropilot FMR67B is a member of the new generation 80 GHz radar level transmitter family. It provides continuous non-contact level measurement for demanding bulk solids applications, even at high temperatures.

With a built-in operating wizard, it guides users easily through commissioning, functional safety and verification tests, making operation extremely convenient.

Its small beam angle makes it especially suitable for installation in narrow silos.

Featuring Heartbeat Technology, it enables online self-verification and self-monitoring, detects abnormal conditions early, improves process safety and increases productivity.

Micropilot FMR67B is designed for level measurement in free space, with a maximum measuring range of 125 m. It delivers excellent focusing performance even in tanks with internal obstacles.
