Pioneering Level Measurement for Bulk Solids

Measuring the level of bulk solids, from fine powders to large rocks, presents a unique set of challenges for industrial processes. Factors like dust, uneven surface profiles, and a high angle of repose can make traditional sensors unreliable. The OPTIWAVE 6400 is an advanced 24 GHz radar level transmitter specifically engineered to overcome these obstacles. It provides continuous, non-contact level measurement for a wide range of solids in silos, stockpiles, and on conveyor belts. Operating on the principle of Frequency Modulated Continuous Wave (FMCW) radar, it emits a continuous signal and analyzes the frequency difference between the transmitted and received waves to calculate the distance to the solid surface. This sophisticated, non-intrusive approach ensures exceptional accuracy and reliability, even across an impressive measuring range of up to 100 meters (328 ft).

A Design for the Toughest Solid Applications

The OPTIWAVE 6400 is built for durability and resilience in the most demanding solid-handling environments. It features a range of antenna options, including a Metallic Horn antenna for standard applications and specialized PP and PTFE Drop antennas for environments with heavy dust and product build-up. The Drop antenna’s ellipsoidal shape and smooth surface are specifically designed to minimize scaling and are unaffected by the angle of repose of the solid material. This eliminates the need for expensive antenna aiming kits, simplifying installation and maintenance. This robust construction allows the sensor to operate reliably in a wide range of process conditions, with temperatures from -50 to +130°C (-58 to +266°F) and pressures up to 16 bar (232 psig). Its ability to withstand these extremes makes it a highly dependable choice for critical applications.

Precision and Agility in Solid Measurement

The use of 24 GHz radar technology is a cornerstone of the OPTIWAVE 6400’s performance. This high-frequency signal provides a highly focused beam, with a small beam angle of just 4° when using the DN150 (6″) PTFE Drop antenna. This narrow beam is crucial for accurate measurement in silos with internal structures or narrow outlets, as it minimizes interfering reflections from the tank walls. The sensor’s high dynamic range enables it to accurately measure levels over long distances and in challenging media. It is an ideal solution for materials with low dielectric constants or those with a lot of dust. The OPTIWAVE 6400 also features built-in configurations for different surface profiles and an Empty Tank Spectrum function that intelligently filters out false reflections caused by tank internals, ensuring reliable readings even in complex geometries. With an exceptional accuracy of ±2 mm (±0.08″), it meets the high-precision requirements of the most demanding industries.

Specific Applications in a Variety of Industries

The versatility of the OPTIWAVE 6400 allows it to serve a diverse range of critical applications. In the mining and aggregates industries, it is used for continuous level measurement in silos and on large stockpiles of materials like stone, coal, and ore. The sensor’s robustness makes it ideal for these environments. In the plastics and chemical industries, it is used to monitor levels of plastic granulates and powders in storage silos and hoppers. In the food and beverage sector, the OPTIWAVE 6400 is a reliable solution for measuring the level of products like coffee beans and grain, where its hygienic design and accuracy are key. Furthermore, it is essential for level monitoring in bunkers and crushers where material flow must be precisely controlled to prevent overfilling and ensure safety.

Flexible Installation and User-Friendly Operation

The OPTIWAVE 6400 is designed for flexible installation and easy operation. It offers a large choice of process connections, including various flange and thread connections, ensuring seamless integration into existing infrastructure. For maintenance and configuration, the device features a large, backlit LCD screen with a 4-button keypad that can be operated via a bar magnet. This allows technicians to configure the device without opening the housing, which is a significant safety benefit in dusty or hazardous environments. The sensor is also compatible with PACTware™ and is supplied with a HART® DD and DTM, providing a user-friendly software environment for advanced configuration and diagnostics. This combination of physical and digital features simplifies both installation and day-to-day use.

Intelligent Diagnostics for Proactive Maintenance

The OPTIWAVE 6400 is more than just a measurement device; it is a smart instrument with built-in diagnostic capabilities. It features extensive device diagnostics in accordance with the NAMUR NE 107 standard, which provides clear status indications for easy troubleshooting and maintenance. These diagnostics allow for continuous self-checking of the device’s health, enabling a proactive maintenance approach. The sensor is also SIL 2/3 certified for safety-related applications, providing an additional layer of reliability in critical processes where safety is a top priority. Its diagnostic features ensure that potential issues are identified early, minimizing unplanned downtime and reducing the total cost of ownership over the sensor’s long service life. This intelligence makes it a reliable asset for any operation.
