Level Monitors

Features and Benefits

The Sentry SR and Sentinel 3000 series offer:

• High accuracy for inventory control without density correction
• Monitoring of turbulent or agitated slurries even when mounted at high angle of incidence
• Filtering software that ignores agitator blades and other obstacles
• Ability to measure varying angles of repose and to convex or concave profiles
• Ability to measure to reflective and non-reflective surfaces
• Operation unaffected by dielectric of materials
• Advanced software for superior performance through dust, steam and other harsh environments
• Operation Immune to effects of temperature, vibration and background noise
• Long-range measurement, up to 250 m and 1,500 m with reflectors
• Narrow beam divergence (0.23°)
• Velocity outputs (on positioners)
• HART protocol
• Explosion-proof enclosures
• Programmable discrete relays
• European and North American Hazloc approvals
• Wide operating temperature range of -40°C to 150°C

 

Typical Applications – Monitoring Liquids
In the chemical, petrochemical, pharmaceutical and other industries, gauge tank levels are used for inventory control on low-dielectric crude and refined products such as:

• Liquid asphalt
• Polymerization reactor vessels (under high pressure)
• Reactor vessels (under vacuum)
• Molten glass
• Ferrous and non-ferrous metals and alloys

Features/Benefits – Monitoring Liquids

• Monitor turbulent or agitated slurries even when the unit is mounted at a high
  incident angle
• Ignore agitator blades and other obstacles with Optech's windowing software
• Detect the surface of a foam layer – unique capability
• High-accuracy inventory control without density correction
• Measure through narrow openings and limited views

Typical Applications – Monitoring Solids
Report material levels for solids in bins, silos and stockpiles such as:

• Polystyrene, nylon and PVC pellets
• Talc and lime powders
• Ore and muck in ore passes
• Wet or dry wood chips
• Stockpiled coal

Features/Benefits – Monitoring Solids

• Measure directly to any surface of a stockpile, cone or inverted cone profile
• Monitor virtually any bin or silo configuration
• Ideal for tall, narrow bins or tricky geometry, where internal structures impede
  other non-contact technologies
• Measure diffuse surfaces at oblique angles – Optech units are unaffected by angle of repose
• Measure reflective and non-reflective surfaces, ranging to the full extreme of bunker geometry
• Superior dust penetration in ranging to darker coarse mesh solids (e.g., coal) – use advanced software to penetrate dust, steam and other difficult environments
• Eliminate inferred readings from complex systems that change characteristics
  after commissioning
