The OPTIWAVE 3500 is a 2-wire 80 GHz radar (FMCW) level transmitter for liquids in hygienic applications. It is designed for continuous, non-contact level measurement in the food and beverage as well as pharmaceutical industry. The device features a flush-mounted PEEK Lens antenna with a small beam angle and dead zone for precise measurement even in small and narrow tanks with agitators. It is equally suited for use on larger tanks, measuring distances of up to 50 m / 164 ft.
