OPTIWAVE 7500
Radar level transmitter for advanced applications with liquids in narrow tanks with internal obstructions
- Continuous, non-contact level measurement in small and narrow tanks with agitators as well as long nozzles
- 80 GHz radar, flush-mounted Lens antenna
- Measuring range: 0…100 m / 328 ft
- -50…+200°C / -58…+392°F; -1…40 barg / -14.5…580 psig
Overview
The OPTIWAVE 7500 is a 2-wire 80 GHz radar (FMCW) level transmitter for demanding liquid applications involving narrow tanks with long nozzles and internal obstructions like agitators or heating coils. Its very small beam angle and negligible dead zone make this FMCW radar the optimal choice for continuous, non-contact level measurement in both extremely small and very high tanks (up to 100 m / 328 ft). The level transmitter is even able to measure through tank roofs made of non-conductive materials. Its PEEK and PTFE Lens antennas are insensitive to deposits and well suited for corrosive environments. As the antennas are flush-mounted, there is no intrusion into the tank.
