Level Measurement
OPTIWAVE 7400
Brand:
Krohne
Radar level transmitter for advanced applications with agitated and corrosive liquids
- Continuous, non-contact level measurement in harsh environments
- 24 GHz radar, Horn or Drop antennas
- Measuring range: 0…100 m / 328 ft
- -50…+200°C / -58…+392°F, up to +700°C / +1292°F in non-ex applications; -1…100 barg / -14.5…1450 psig (higher on request)
- 2-wire, loop-powered, with HART®7
- Distance piece for non-ex applications with molten salt or other high temperature liquids of up to +700°C / +1292°F
- PTFE or PEEK Drop antennas:
- Insensitive to condensation
- Small beam angle (4° with DN150 / 6″ PTFE antenna)
- Ellipsoidal shape and smooth surface to minimise scaling
- PTFE flange plate protection for corrosive media
- New DN100 / 4" Drop antenna for distances up to 80 m / 262.5 ft
- 316L Metallic Horn antennas with optional purging system
- Heating / cooling systems to prevent crystallisation or build-up in Metallic Horn antennas
- TBM (Tank Bottom Management) ensures reliable measurement even in empty tanks:
- dedicated algorithms to filter and compensate for irregular radar wave reflections that occur at tank bottom when the vessel is empty
- allows for quick and easy commissioning of tanks regardless of their size, material or geometry
- ±2 mm / ±0.08″ accuracy
- METAGLAS® second sealing barrier for toxic and dangerous liquids
- Antenna extensions to suit any nozzle length
- Empty tank spectrum function eliminates false reflections caused by tank internals
- Large choice of flange and thread connections
- Quick Coupling system permits removal of the converter under process conditions and 360° rotation for easy reading of display
- Converter compatible with all OPTIWAVE 7300 C flange connections
- Large, backlit LCD screen with 4-button keypad for operation with bar magnet; no need to open the housing cover
- PACTware™, HART® DD and DTM provided free of charge with full functionality
- Extensive device diagnostics acc. to NAMUR NE 107
- SIL 2/3 certified for safety-related applications
- 3-year warranty
