Silopilot FMM50 - Electromechanical Level measurement
Silopilot FMM50 is an electromechanical level system. Depending on the sensing
weight, the level can be measured in bins or silos with dusty, fine-grained or
coarse-grained bulk solids or in tanks with liquids.

Benefits
-
High reliability level measurement of powdery, fine-grained or coarse-grained bulk solids
-
Safe measurements in extremely dusty environments
-
Fully electronic digital minimum fail-safe control, therefore no running down of the sensor
weight into the silo outlet and no risk to the conveying systems -
Quick menu-guided local operation using a 4-line text display
-
High performance three-phase engine (traction power up to 500N) using a single-phase supply
voltage by employment of a converter, therefore simple electric supply -
Optional design with certification for application in areas subject to dust explosion hazard zones
20, 21 and 22 (measuring zone) or zones 21 and 22 (device zone), category 1/2D
Field of application
For level measurement in bunkers or silos for dusty, fine or coarse-grained bulk products, or in tanks containing liquids.
