The Endress+Hauser Micropilot FMR52 is a 26GHz K-band non-contact radar level transmitter engineered for continuous level measurement in aggressive chemicals, strong acids/alkalis, and sterile hygienic storage vessels (-40 to +200°C, vacuum to 25 bar, max range 60m).
100% Full PTFE Flush Antenna: Completely isolates metal process parts to prevent severe chemical acid corrosion and eliminate sanitary dead legs (ASME BPE & EHEDG certified).
±2 mm High Precision: Provides accurate, non-contact continuous liquid level tracking unaffected by heavy vapor, density changes, or temperature fluctuations.
Multi-Echo Tracking & SIL2/SIL3: Advanced digital signal filtering eliminates false echoes from tank agitators while securing SIL2/SIL3 functional safety compliance.
Fast Supply & Flexible Payment: Original factory-new stock with quick global dispatch, featuring direct RMB bank transfer support for smooth cross-border trade.
The Endress+Hauser Micropilot FMR52 is a 26GHz K-band non-contact radar level transmitter designed specifically for highly corrosive chemicals (acids/alkalis) and sterile hygienic storage tanks. Featuring a fully PTFE-encapsulated flush antenna, it completely resolves metal antenna corrosion in concentrated acids and eliminates dead legs where bacteria proliferate in sanitary processes.
Plant engineers managing aggressive chemicals or bio-pharmaceutical reactors frequently encounter destructive operational failures. The FMR52 directly solves these field issues:
Plant Loss: Metal horn antennas corrode and thin out rapidly in 98% sulfuric acid or hydrofluoric vapors, allowing toxic fluid to seep into electronics and forcing unscheduled shutdowns.
FMR52 Solution: Process connections and antennas feature a 100% seamless PTFE cladding that completely isolates metal components from corrosive vapors.
Plant Loss: Micro-gaps around standard threaded seals trap residual product that CIP cycles cannot reach, breeding bacteria and ruining multi-million-dollar pharmaceutical batches.
FMR52 Solution: Certified to EHEDG and 3-A standards, the flush PTFE antenna leaves zero dead spaces, enduring repeated high-temperature SIP steam sterilization cycles.
Plant Loss: Heavy agitation vortexes and dense vapor clouds cause signal loss, leading to feed pump dry-running or dangerous vessel overfills.
FMR52 Solution: Multi-Echo Tracking algorithms filter out agitator reflections and wave interference, securing steady ±2 mm level measurement.
