Field of application
For applications in aggressive liquids Micropilot FMR52 offers extraordinary advantages with its completely PTFE-filled and flush-mounted horn antenna. The FMR52 is also the sensor for hygiene-sensitive applications in the food and life sciences industry - ASME BPE, USP Class VI, 3-A and EHEDG approvals. Micropilot is used for continuous, non-contact level measurement of liquids, pastes and slurries. The measurement is not affected by changing media, temperature changes, gas blankets or vapors.
Flush-mounted, completely PTFE-encapsulated horn antenna.
Process connections: Flush-mounted with cladded flange, process connections for hygiene requirements (Tri-Clamp, 11851)
Temperature: -196 to +200°C (-320,8 to +392°F)
Pressure: -1 to +25bar (-14.5 to +362psi)
Maximum measuring range: 40m (131ft), 60m (197ft) for enhanced dynamics
Accuracy: ±2mm
K-band: 26GHz
International explosion protection certificates, overfill prevention WHG, SIL, hygienic certificates, marine approval
Benefits
Hardware and software developed according to IEC 61508 up to SIL3 (in homogeneous redundancy)
Reliable non-contact measurement even for changing product and process conditions
HistoROM data management concept for fast and easy commissioning, maintenance and diagnostics
Highest reliability even in the presence of obstructions in the vessel due to new Multi-Echo Tracking evaluation
Heartbeat Technology for a cost-effective and safe plant operation during the entire life cycle
Seamless integration into control or asset management systems and intuitive, menu-guided operation concept (on-site or via the control system)
World's easiest proof test concept for SIL and WHG saves time and cost
