Overview
The OPTIWAVE 5400 is a 2-wire 24 GHz radar (FMCW) level transmitter for liquids in basic process applications. It is particularly designed for continuous, non-contact level measurement in the chemical, petrochemical, power as well as oil and gas industry. It can be equipped with a PP Drop antenna for condensing atmospheres and corrosive media but features also Metallic Horn antennas. Due to its high dynamic range, the 24 GHz radar can measure distances up to 100 m / 328 ft.
Product features and options depend on device configuration: Contact us to make sure that your preferred functionality can be combined in one device.
- 2-wire, loop-powered, with HART®7
-
PP Drop antenna:
- Insensitive to condensation
- Small beam angle (5° with DN150 / 6″ Drop antenna)
- Ellipsoidal shape and smooth surface to minimise scaling
- PP flange plate protection and cladded antenna extensions for corrosive media
- New DN100 / 4″ Drop antenna for distances up to 80 m / 262.5 ft
- 316L Metallic Horn antenna with optional purging system
-
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
- 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
- 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
