Endress+Hauser FMU30-AAHEAAGGF – Free-Space Radar Level Transmitter | Micropilot M Series
Engineering Background
The Micropilot M FMU30 is Endress+Hauser’s compact, non-contact free-space radar level sensor engineered for reliable continuous level measurement of bulk solids and liquids in open or enclosed vessels. Operating at 6 GHz with a focused beam, it eliminates the mechanical wear and media contact inherent in float, ultrasonic, or guided-wave technologies.
Product Positioning
The FMU30-AAHEAAGGF is the fully specified variant combining a 4–20 mA / HART output, polypropylene process connection, and IP68/NEMA 6P enclosure — purpose-built for demanding industrial environments including cement silos, aggregate bins, wastewater sumps, and chemical storage tanks. Konmask.com supplies this unit as new-in-box OEM stock with full traceability documentation.

System Architecture & Signal Flow
The FMU30 transmits a frequency-modulated continuous wave (FMCW) radar signal at 6 GHz toward the product surface. The reflected echo is processed by the integrated DSP to calculate time-of-flight, which is converted to a level value and output as a 4–20 mA signal proportional to the configured span. HART communication is superimposed on the 4–20 mA loop, enabling simultaneous analog control and digital diagnostics without additional wiring. The unit integrates directly with Endress+Hauser RIA15/RIA45 loop indicators, Siemens SIMATIC, Rockwell ControlLogix, and any HART-compatible DCS or PLC input card.

Technical FAQ
Q: Can the FMU30-AAHEAAGGF measure liquids as well as solids?
A: Yes. It is rated for both bulk solids (up to 15 m) and liquids (up to 5 m). Dielectric constant (Dk) of the medium affects maximum range on liquids; Dk ≥ 1.6 is recommended.
Q: Is HART configuration software required for commissioning?
A: No. Basic level measurement can be configured using the onboard DIP switches (empty/full calibration). Advanced HART parameterization requires a HART communicator (e.g., Endress+Hauser Field Xpert or any 475/375 HART handheld) or FieldCare/DeviceCare software.
Q: What is the minimum distance (blocking distance) from the antenna?
A: The blocking distance is 0.1 m (10 cm) from the antenna face. Product surface must not enter this zone during normal operation.
Q: Is this unit ATEX / IECEx certified for hazardous areas?
A: The base FMU30-AAHEAAGGF variant is non-Ex. ATEX/IECEx versions are available under different order codes. Contact Konmask for Ex-rated variants.
Q: Can I integrate this with a Siemens S7 PLC?
A: Yes. The 4–20 mA output connects directly to any standard analog input module (e.g., SM 331). HART data can be accessed via a HART multiplexer or HART-capable AI module (e.g., Siemens ET 200SP AI Energy Meter).
