Overview
The OPTIWAVE 1530 is a 2-wire 80 GHz radar (FMCW) level transmitter for cost-effective, non-contact level measurement of solids. It is also designed for measuring agitated and poorly reflecting liquids. Its flush-mounted DN70 / 3” Lens antenna has a beam angle of just 4°. As a result, the level radar provides reliable level measurement, particularly in extremely narrow tanks or containers, without causing interfering reflections.
The compact radar unit is made entirely of PVDF and is therefore extremely durable. With its high dynamic range and fully potted electronics, the OPTIWAVE 1530 is ideal for demanding environments with dusty atmospheres and vibrations, making it particularly suitable for mining applications with crushers, conveyor belts, stockpiles or small bunkers. The 80 GHz radar is therefore ideal for measuring a wide range of materials - from rocks and ROM ore to gravel, granulate and powders. It is also suitable for applications with grain and animal feed, pellets or waste in silos with a height of up to 15 m / 49.3 ft. In addition, the OPTIWAVE 1530 is also used in more demanding applications with agitators and liquids with a low εr value, such as edible oil.
The level radar comes IP68 rated, offering additional safety in very dusty areas or outdoor environments that are exposed to heavy rain or flooding. The 3'' threaded connection of the radar is unique in its device class and offers flexible installation options. The level transmitter can e.g. be used with existing flanges without protruding into the nozzle of tanks and silos. It is available with bespoke accessories such as brackets and aiming kits, low-pressure flange or purge port connection.
The OPTIWAVE 1530 utilises the OPTICHECK technology built-in device diagnostics. This enables continuous self-checking of the device status. In addition, on-site verification and monitoring of configuration and readings can be carried out via Bluetooth® in combination with the KROHNE OPTICHECK Level Mobile app. There is no need to interrupt the process, climb onto silo roofs and other equipment or work in confined installation areas. This simplifies operation and maintenance and contributes to increased occupational safety.
