The PiloTREK WT–300 non-contact level sensor radar utilise 80 GHz FMCW radar technology—the most advanced in industrial measurement—for bulk solids in food processing, agriculture, construction materials, chemicals, and mining. They deliver millimeter accuracy across light powders to large-particle solids.
Designed for non-contact measurement, the PiloTREK WT–300 radar level transmitter can measure level, volume and weight in a wide range of industrial applications.
Beyond level, volume, and weight measurement, the family includes threshold functions to eliminate false echoes. The level sensor radar is compatible with HART®-enabled NIVELCO EView2, MultiCONT universal process controller, MonoCONT smart field display & data logger, and PACTware™ software, or programmable via Bluetooth® with the MobileEView app.
This radar sensor is intended for applications involving powders, granular materials and free-flowing bulk solids.
The reflection of the millimeter-waves is highly dependent on the dielectric constant of the medium. The actual measurable distance achievable with microwave level measurement is limited when the dielectric constant (εr) is low.
The measurement principle of a level transmitter using a millimeter-wave signal is based on measuring the total time of flight of the measuring microwave signal. The speed of propagation of millimeter-wave signals in the air, gases, and vacuum is almost constant regardless of temperature and medium pressure, so the measured distance does not depend on the physical parameters of the intermediate medium.
The PiloTREK WT–300 radar level transmitter operates on a continuous-wave frequency-modulated radar (FMCW) principle, utilizing the 80 GHz (W-band) frequency. A portion of the millimeter-wave continuous wave energy radiated by the level transmitter antenna is reflected from the measured surface, depending on the material to be measured. The distance of the reflecting surface is calculated with high accuracy by the electronics from the frequency shift of the reflected signal and converted into a distance, level, mass, or volume signal by the electronics
Thanks to its 80 GHz FMCW technology, the radar level transmitter is much less sensitive to the presence of clutter than previous-generation radars. It now has an easy-to-use, flexible threshold management (EView2) that allows echoes from clutter in the tank to be easily masked if necessary. The threshold curve is designed to mask unwanted echoes from the measurement. Echo peaks below the threshold are not included in the evaluation.
The Bluetooth® option on the PiloTREK W–300 Series allows for convenient device setup and diagnostics via the NIVELCO MobileEView app for Android or iOS or the free EView2 software down load for laptops.
