Radar (FMCW) level transmitter for liquids with hygienic requirements
• Continuous, non-contact level measurement in high and narrow, small and agitated tanks
• 80 GHz radar, gasket-free Lens antenna
• Measuring range: 0…50 m / 164 ft
• -40…+150°C / +302°F; -1…25 barg / -14.5…362 psig

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.

The OPTIWAVE 3500 fits applications with any finished or raw product – from raw milk, wine or juice to solvents. As the radar withstands process temperatures up to +150°C / +302°F and pressures up to 25 barg / 362 psig, it can be used in CIP/SIP cleaning procedures. The OPTIWAVE 3500 offers a large choice of hygienic process connections. It comes with extensive device diagnostics as well as HART®7 communication.

Product highlights
