The OPTIWAVE-M 7400 C is a 2-wire 24 GHz radar (FMCW) level transmitter for non-contact cargo level measurement. This marine level radar is a highly accurate and reliable instrument for ullage indication. Equipped with heavy-duty stainless steel housing, it is designed to withstand the roughest conditions on ships. If necessary, the signal converter of the level transmitter can be replaced during cargo operations. The Drop antenna option makes it ideal for measuring sticky/contaminating liquids or dust-laden atmospheres where product build-up is likely to occur.
Show moreThe extremely rugged cargo radar features a backup display for redundant indication. Cargo operations may continue with a man on deck, if level information is lost on the main monitoring station. The OPTIWAVE-M 7400 level transmitter is the perfect fit for applications with the CARGOMASTER® solution for onboard tank monitoring and alarm. It holds IEC (Ex IIC) intrinsic safety certification as well as approvals of all major marine classification societies.
