OPTIWAVE 5200 C – Compact / horizontal version with PP Wave Horn antenna

Radar (FMCW) level transmitter OPTIWAVE 5200 C – Compact / horizontal version with PP  Wave Horn  antenna

The OPTIWAVE 5200 is a 2-wire 10 GHz radar (FMCW) level transmitter for liquids, pastes and slurries. It is particularly suited for continuous, non-contact level measurement in storage or process tanks with small process connections or where it is difficult to access the tank roof (remote version recommended).

The OPTIWAVE 5200 is SIL2-compliant according to IEC 61508-2 for Safety Instrumented Systems (SIS). Its PP or PTFE Wave Horn antenna options make it ideal for measuring the level of corrosive liquids. Additional ease of use comes from the quick coupling system which permits 360° rotation of the housing or its removal under process conditions.

Product highlights

  • Measurement of level, distance, volume, reflection and flow rate
  • Quick coupling system: converter is rotatable and removable under process conditions
  • Gasket-free PP or PTFE Wave Horn antennas for corrosive media
  • Modular housing and antenna design
  • Keypad accessible without opening the housing cover
  • Remote converter up to 100 m / 328 ft away from the antenna
  • PACTware™ and DTMs provided free of charge and with full functionality
  • SIL2-compliant according to IEC 61508-2
  • 2-wire: 4…20 mA/HART®, PROFIBUS PA, FOUNDATION™ Fieldbus

Typical applications

  • Level measurement in storage and process tanks
  • Tanks with small process connections (≥112")
  • Tanks with difficult access to tank roofs (remote version)
  • Hazardous area applications or Safety Instrumented Systems (SIS)
  • Level measurement of liquids, e.g.:
    • Fertilizers, solvents, alcohols, bases, acids, ferric chloride
    • Condensates, cooling water
    • Hydrocarbons, hydraulic oil
    • Molasses, vegetable oil
    • Flocculent, sludge
    • Molten steel
