Field of application
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.
For level measurement in bunkers or silos for dusty, fine or coarse-grained bulk products, or in tanks containing liquids.
Process connection: Flange
Temperature: -40 to +230°C (-40 to +446°F)
Pressure: 0.8 to 3bar (11.6 to 43.5psi)
Measuring range: 70m (230ft)
Accuracy: ±5cm (1.97")
International explosion protection certificates
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
