NG # 04011-HW-KROHNE-045
The OPTIWAVE 1520 is a 2-wire 80 GHz radar level transmitter for basic applications with liquids and solids. Its PVDF Lens antenna and compact housing make it particularly suitable for use in confined spaces as well as harsh process and environmental conditions such as outdoor applications, where a high degree of robustness is required. The level radar is therefore the ideal choice for cost-effective level measurement of sewage sludge and wastewater as well as treated water, e.g. in pumping stations, screw lifting stations or water basins.

With its front-flush antenna design and its narrow beam angle, the cost-effective 80 GHz radar can also be used in small open tanks or pressurised vessels with internal obstructions where level measurement with dead zones is not an option. Due to its extremely high dynamic range, the OPTIWAVE 1520 is also able to provide reliable readings in the event of condensation or moving surfaces.
