DR6500 Radar Level Transmitter

Brand: Drexelbrook

Drexelbrook DR6500 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 DR6500 provides accurate and reliable readings in process conditions with temperatures up to 150° C / 300° F and pressures up to 580 psig (40 barg). 

It offers flange or thread connections as well as an optional 4.4" (112 mm) antenna extension for the 1.5” antenna (DN40).

Approvals for use in hazardous areas are also available.

The level transmitter comes with HART®7 communication.
Features
  • Process conditions up to 150° C / 300° F and 362 psig (25 barg)
  • Small dead zone and beam angle for small and narrow tanks
  • Flush-mounted PEEK Lens antenna hence no intrusion into tank
  • Extremely high dynamics for clear vision despite dusty atmospheres or low reflective media
  • 3 Year Warranty
