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
