Microwave Solids Flow Monitors Models SFD-2 & SFI
- Best Value In Solids Flow Detection
- Superior Application Versatility
- Excellent Sensitivity
- Indicate Flow/No-Flow In Chutes, Feeders, and Pipelines
- On/Off Flow Detector (SFD-2)
- Analog Output Indicator (SFI)
- Hazardous Location Approval
- Senses Light And Heavy Materials, Small And Large Particles
- Non-Contact Sensor Detects Flow Through Most Non-Metallic Surfaces
- Non-Intrusive Flush Mounting - No Probe Protruding Into Material Flow
- SFD-2 Provides Relay Outputs and Convenient Remote Electronics
- SFI Solids Flow Indicator Provides Variable Analog Signal
- Sensors Include CSA Class II, Division I Approval for Hazardous Locations
The SFD-2 and SFI use low-power microwaves to sense motion within the chute or pipeline being monitored. Microwaves are virtually unaffected by ambient noise, light, heat, humidity, pressure, vacuum, high or low temperatures, or dust. This provides maximum effectiveness in typical industrial application environments. These advantages over sonic or mechanical flow monitors make microwave technology the best choice for solids flow monitoring.
