Krohne, a provider of industrial process instrumentation, is introducing the new 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 technology provides a solution suitable for industries such as metals, minerals, mining, and water and wastewater, delivering accurate, non-contact measurement of solids and liquids.
The OPTIWAVE 1530 is a cost-effective solution with a measuring range of 0-15m, making it suitable for small to medium silos, stockpiles, bunkers, and tanks. The OPTIWAVE 1560 extends the measuring range to 30m for long-range measurement in tall silos, large tanks, and deep vessels. Both models provide drift-free, maintenance-free operation without requiring recalibration over the product’s lifetime, reducing total cost of ownership.
Designed for durability, both models feature a compact, robust design with fully potted electronics to protect internal components from dust, condensation, vibration, and shocks. The flush-mounted, concave PVDF lens antenna provides chemical resistance and self-draining to prevent buildup, maintain a stable radar signal, and ensure consistent performance, even with condensation present.
With a narrow 4° beam angle, these transmitters achieve exceptional accuracy in tight spaces and in vessels with internal obstructions by avoiding interference from walls or fixtures. Their high dynamic range ensures reliable performance on dusty surfaces, foamy or agitated liquids, condensation, or poorly reflecting media. Virtually no dead zone maximises the usable measurement range, even in small tanks.
Installation is simplified with a 3” 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 protects against heavy rain, outdoor dusty environments, and flood-prone areas.
Commissioning and operation are streamlined using Bluetooth connectivity with the OPTICHECK Level Mobile App, facilitating safe, remote setup from the ground; no climbing tanks or silos required. Pre-configured application templates provide step-by-step guided setup, while the flexibility to switch measurement parameters for other applications adapts to changing process needs. HART communication with OPTICHECK DTM enables quick integration into control systems, and built-in OPTICHECK diagnostics 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. The devices include a 5m shielded cable, come with a 3-year warranty, and offer accessories such as brackets, flanges, and weather covers.
With the launch of the OPTIWAVE 1530 and 1560, Krohne delivers a new level of precision, reliability, and versatility in level measurement technology. Both models combine robust construction with cutting-edge radar performance, giving industries the accuracy they require with the ease of installation and maintenance they demand, helping customers to optimise processes, reduce costs, and ensure long-term measurement confidence.
