The OPTIWAVE 6500 is a 2-wire 80 GHz radar (FMCW) level transmitter for demanding applications with powders in very dusty atmospheres. With its small beam angle, this radar is particularly suited for continuous, non-contact level measurement in high and narrow silos, hoppers or buffer storage containers up to 100 m / 328 ft. Due to the high signal dynamics of the FMCW radar, the level transmitter is ideal for low-reflective media, dust, uneven surfaces or tanks with obstacles. As it features a flush-mounted PEEK Lens antenna, there is no intrusion of the antenna into the tank.

The OPTIWAVE 6500 provides accurate and reliable readings in process conditions with temperatures up to +150°C / 302°F and pressures up to 40 barg / 580 psig. It offers flange or thread connections as well as an optional 112 mm / 4.4" antenna extension for the DN40 / 1.5”antenna. Approvals for use in hazardous areas are also available. The level transmitter comes with HART®7 communication.

Product highlights

• 2-wire, loop-powered, with HART®7
• High dynamics for clear vision despite dusty atmospheres or low reflective media
• Empty tank spectrum function eliminates false reflections caused by tank internals
