Product Description
Product Description: E+H FMR50 Radar Level Transmitter/Gauge
The E+H FMR50 Radar Level Transmitter is a high-precision, non-contact level measurement device designed for industrial applications requiring reliable and continuous monitoring of liquids, slurries, and interfaces in tanks, silos, or reactors. Utilizing Frequency Modulated Continuous Wave (FMCW) radar technology at 26 GHz, it delivers exceptional accuracy and stability even in challenging conditions such as foam, vapor, dust, or temperature extremes. Ideal for industries ranging from chemical processing to water treatment, the FMR50 combines advanced engineering with user-friendly features to optimize process efficiency and safety.
Key Technical Features The FMR50 operates with a measurement range of up to 30 meters (98.4 feet), achieving an impressive accuracy of ±1 mm under static conditions and ±3 mm in dynamic environments. Its 26 GHz frequency ensures a focused radar beam, minimizing interference from tank walls, agitators, or internal structures. The device supports a wide process temperature range from -40°C to +200°C (-40°F to +392°F), with optional configurations extending to +400°C using cooling accessories, making it suitable for high-heat applications like steam boilers or reactors.
Constructed with stainless steel (316L) or aluminum housing, the FMR50 is built to withstand corrosive and abrasive environments. Antenna options include PTFE-coated parabolic antennas for general use and PVDF/PP horn antennas for aggressive media, ensuring compatibility with chemicals, acids, or solvents. The IP66/IP67 and NEMA 4X protection ratings guarantee durability in outdoor installations, heavy rainfall, or dusty settings.
Advanced Functionality The FMR50 integrates seamlessly into industrial automation systems via 4-20 mA HART, PROFIBUS PA, or Foundation Fieldbus outputs, enabling real-time data transmission to PLCs or DCS. Its Bluetooth-enabled configuration via the Field Xpert mobile app allows wireless setup, diagnostics, and troubleshooting, reducing downtime and maintenance costs. The device also features Heartbeat Technology, a self-monitoring function that provides predictive maintenance alerts and ensures long-term operational reliability.
Certifications and Compliance Certified for global use, the FMR50 meets ATEX, IECEx, SIL2, CE, FM, and CSA standards, making it explosion-proof and safe for hazardous areas (Zone 0/1/2). It complies with stringent industry regulations for functional safety, environmental resilience, and electrical compatibility.
Applications and Industries The FMR50 excels in diverse sectors:
