This series of 80GHz FMCW (Frequency Modulated Continuous Wave) radar level transmitters represents next-generation non-contact level measurement technology. With an operating frequency in the 76-81 GHz millimeter-wave band, the instrument offers dramatically improved focusing, resolution, and penetration compared to lower-frequency radars.
It is specifically engineered for demanding industrial applications involving bulk solids (powders, granules, aggregates) and liquids, even under extreme conditions such as heavy dust, steam, high temperatures, or rapid agitation. The compact RF architecture and advanced built-in algorithms ensure stable, maintenance-free operation and long-term reliability in silos, bunkers, storage tanks, process vessels, and more.
Measuring principle — FMCW radar (76–81 GHz, 5 GHz bandwidth)
Maximum measuring range — Up to 60 m
Blind zone — Nearly zero (very small dead band for maximum usable range)
Beam angle — 3° (ultra-narrow for reduced false echoes)
Accuracy — High resolution and precision, comparable to leading ±1 mm performance in class-leading applications
Process conditions — Excellent performance in extreme dust, high temperature, vapor, foam, and fast agitator environments
Antenna design — Optimized for strong reflection on sloped solids (minimal aiming required)
Communication & Operation —
4-wire: RS-485 Modbus protocol
2-wire: TTL serial or HART protocol
Local operation via push buttons
PC configuration software
Bluetooth via mobile app for wireless control
Remote debugging and OTA firmware upgrades
Installation — Simple and flexible; narrow beam reduces constraints from internal structures
The instrument operates on the FMCW radar principle. A continuous frequency-modulated microwave signal (76–81 GHz) is transmitted via the antenna and propagates at the speed of light. When the signal reaches the surface of the medium, part of it is reflected back to the antenna due to the change in dielectric constant.
The frequency difference (beat frequency) between the transmitted and received signals is proportional to the distance (time-of-flight). Advanced digital signal processing converts this into a precise level value. The high frequency and wide bandwidth provide excellent resolution, while the narrow beam and advanced algorithms suppress interference from agitators, dust, or false echoes — ensuring stable output even in turbulent or dusty conditions.
This professional-grade 80GHz radar level transmitter combines cutting-edge technology with user-friendly features, offering a reliable, cost-effective solution for your most demanding level measurement challenges — inspired by the performance standards of global leaders in industrial instrumentation.
