ENVEA Reflex RD5xx Series - Radar Level Measurement
The ENVEA Reflex RD5xx series measures levels without contact using 80 GHz radar, with ranges from 10 to 30 metres and 1 mm resolution.
With the Reflex RD5xx product family, ENVEA offers a new range of continuous level measurement solutions for bulk solids and liquids. The series includes four variants – Reflex RD520, RD530, RD540 and RD560 – designed for different measuring ranges and requirements in the bulk solids and process industries.
Level measurement in silos and tanks can be challenging due to dust, internal structures, narrow vessel geometries or changing material surfaces. The Reflex RD5xx sensors therefore use 80 GHz FMCW radar technology in the 77 to 81 GHz frequency range. Depending on the model, measuring ranges from 10 to 30 meters are available. The sensors provide a resolution of 1 mm, repeatability of ±1 mm and, depending on the model, accuracy of up to ±2 mm.
A high dynamic range and a narrow beam angle of up to 4° help ensure stable measurement results, even in tall or narrow silos. The minimal dead zone also supports more complete use of the available vessel volume.
Non-contact measurement reduces maintenance requirements
One of the key advantages of radar technology is its non-contact measurement principle. As the sensor does not come into contact with the material, mechanical wear and material-related measurement deviations are reduced. Regular recalibration is not required in many applications. This makes the technology particularly suitable for dusty, abrasive or changing bulk materials.
Typical applications include the cement and building materials industries, precast concrete plants, ready-mix concrete facilities, energy-from-waste plants and other areas of the process industry. Suitable materials include lime, cement, fly ash, GGBS, powders and granulates, as well as various liquids.
For demanding industrial environments, the sensors feature a PVDF housing and antenna and are rated to IP68. The permitted process range extends from -25 °C to +80 °C at pressures of up to 5 bar(g).
Easy commissioning via Bluetooth
The sensors have also been designed for simple commissioning and operation. Via a Bluetooth interface, they can be configured and diagnosed from ground level. The “Level Device Configurator” app guides users step by step through the setup process. Predefined silo, tank and vessel shapes further simplify configuration.
The sensors can be used as standalone solutions or combined with ENVEA’s Shield Lite and Silo Trend systems. This enables level and inventory data to be used for remote monitoring. Companies can gain greater transparency over material stocks, improve production and delivery planning, and reduce the risk of unplanned production interruptions.
With the Reflex RD5xx family, ENVEA provides a flexible solution for continuous level measurement that combines precise radar technology with simple commissioning and low maintenance requirements.
