Loop-powered level radar - Micropilot M

Micropilot M of Endress+Hauser India, Mumbai, complies with the requirement of simple commissioning and operation in using modern radar technology in industrial measurement instrumentation. The large, four-line, plain-text display permits menu-driven on-site operation. The user is guided (step by step) through the complete basic calibration. Micropilot M offers the radar-signal as an envelope curve also on the instrument display. This provides information concerning the reliability of the instrument. A graphic operating tool (ToF-tool) free of charge permits simple commissioning, optimising, diagnosis and the documentation of measuring points. In Micropilot M, a second frequency of approx. 26GHz is introduced apart from the known frequency of approx. 6GHz. The higher frequency permits using the small 1-1/2inch horn antenna, particularly in small nozzles and smaller tanks. The narrow beam angle avoids interfering reflections by baffles in tanks. Beside that, an accuracy of +/-3mm is achieved. The new instrument line of Micropilot M in loop-powered technology comprises three versions: FMR 230 (horn antenna) approx. 6GHz; FMR 231 (rod antenna) approx. 6GHz; and FMR 240 (small horn antenna) approx. 26GHz. They communicate via HART protocol respectively, the connection to PROFIBUS-PA or Foundation Fieldbus. The assignment of the three instruments has been clearly determined.
