- Cost-effective non-contact level measurement in tanks (up to 5 bar / 72.5 psi), (waste)water basins, pumping stations, etc.
- Compact and robust 80 GHz radar with flush-mounted PVDF Lens antenna; waterproof (IP68) version also available
- Measuring range: 0…10 m / 32.8 ft
- 2-wire 4…20 mA HART®7; user-friendly commissioning via Bluetooth® using the OPTICHECK Level Mobile app
Overview
The OPTIWAVE 1520 is a 2-wire 80 GHz radar (FMCW) 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. It is equally designed for use in small silos with granulates such as sand or other products. The level transmitter is also available as an IP68-rated waterproof version, designed to withstand heavy rainfall and flooding.
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.
Commissioning is easily carried out via Bluetooth® using the KROHNE OPTICHECK Level Mobile app or via HART® with the OPTICHECK DTM. The OPTIWAVE 1520 also utilises self-diagnostics of the OPTICHECK technology built-in. This enables continuous device testing and verification including reporting on site without process interruption and removal of the radar.
