KROHNE Introduces OPTIWAVE Radar Level Transmitters

KROHNE has launched the OPTIWAVE 1530 and OPTIWAVE 1560 radar FMCW level transmitters for solids and liquid applications, including small to tall silos, narrow tanks, stockpiles, bunkers and vessels with internal obstructions.

The OPTIWAVE 1530 provides a cost-effective solution with a measuring range of 0-15 m (49.2 ft), making it suited for small to medium silos, stockpiles, bunkers and tanks. The OPTIWAVE 1560 extends this capability to 30 m (98.4 ft) for long-range measurement in tall silos, large tanks and deep vessels. Both models deliver drift-free, maintenance-free operation without the need for recalibration over the lifetime of the product.

Built for durability, both models feature a compact design with fully potted electronics to protect internal components from dust, condensation, vibration and shocks. The flush-mounted, concave PVDF lens antenna offers chemical resistance and a self-draining design to prevent buildup, maintain a stable radar signal, and ensure consistent performance, even with condensation present.

With a 4° beam angle, these transmitters achieve accuracy in tight spaces and in vessels with internal obstructions by avoiding interference from walls or fixtures. Their dynamic range ensures reliable performance on dusty surfaces, foamy or agitated liquids, condensation, or poorly reflecting media. Virtually no dead zone maximizes the usable measurement range, even in small tanks.

Installation is simplified with a unique 3-inch threaded connection that fits standard flanges and accessories without protruding into nozzles, eliminating potential measurement interference. For extreme conditions, an optional IP68-rated waterproof version offers maximum protection in heavy rain, outdoor dusty environments and flood-prone areas.

Commissioning and operation are streamlined using Bluetooth connectivity with the OPTICHECK Level Mobile app, enabling safe, remote setup from the ground, no climbing tanks or silos required. Pre-configured application templates in the app offer step-by-step guided setup, while flexibility to switch measurement parameters for other applications helps adapt to changing process needs. HART communication with OPTICHECK DTM allows quick integration into control systems, and built-in OPTICHECK diagnostics continuously monitor device health to reduce downtime.

Maintenance and compliance are streamlined with on-site verification that requires no process interruption, a one-click verifiable status report for documentation and advanced algorithms, including Tank Bottom Management, to filter false echoes and ensure accurate empty tank detection, even in challenging media. Each device includes a 5 m (16.4 ft.) shielded cable, comes backed by a three-year warranty, and offers a range of accessories such as brackets, flanges and weather covers.
