OPTIWAVE 1010 – Version with aluminium housing

Radar (FMCW) level transmitter OPTIWAVE 1010 – Version with aluminium housing

The OPTIWAVE 1010 is a 2-wire 6 GHz radar (FMCW) designed for continuous level measurement of clean liquids. It is welded to a bypass chamber or magnetic level indicator (MLI). This radar is a cost-effective solution for simple applications in industries like the chemical, power, water and wastewater industry. It comes pre-configured and ready to use. The dual process seal system permits the removal of the converter under process conditions. PACTwareTM, HART® DDs and DTMs are provided free of charge with full functionality.

Product highlights

  • Welded to a bypass chamber with optional IP 68 indicator
  • No minimum dielectric constant when equipped with a float
  • Dual process seal system with Metaglas® or Metapeek
  • Aluminium or stainless steel housing
  • Pre-configured in the factory and ready to use (plug & play)
  • Accuracy: ± 5 mm / 0.2" uncertainty
  • 2-wire, 4…20 mA/HART®
  • PACTware™, HART® DDs and DTMs provided free of charge with full functionality

Typical applications

  • Clean liquids in bypass chambers or magnetic level indicators, e.g. solvents, alcohols, bases, condensates, liquefied gases, hydrocarbons, hydraulic or motor oil, engine coolants, washing fluids, cooling or drinking water
