On Hand: 0
The OPTIWAVE 7400 is a 2-wire 24 GHz radar (FMCW) level transmitter for liquids in harsh environments like tanks with agitators containing corrosive media. It is particularly designed for continuous, non-contact level measurement under extreme conditions prevalent in the chemical, petrochemical, power, metal or oil and gas industry. The device features Metallic Horn antennas as well as PTFE and PEEK Drop antennas for measuring distances up to 100 m / 328 ft. The Drop antennas are perfectly suited for aggressive liquids in tanks. In applications with toxic and dangerous products, this radar device can be equipped with a METAGLAS® second sealing barrier.
