Field of application
Liquicap FMI52 is a reliable fully insulated rope probe for continuous level monitoring in liquids, particularly in small tanks, build-up forming media and extremely high temperatures – especially for large measuring ranges. The measurement is independent of the dielectric constant (dc). Used in conjunction with Fieldgate FXA320 (remote measured value interrogation using Internet technology), Liquicap is an ideal solution for Inventory Management Solutions.
Device is independent of the dielectric constant (dc) as of a liquid conductivity of 100μS/cm and allows measurement of various liquids without the need for recalibration.
Process connections: Flanges and threads
Process pressure: Vacuum to +100bar (vacuum to 1,450psi)
Measuring range: 0.42 to 10.0m (1.38 to 33ft)
Temperature: -80 to +200°C (-112 to +392°F)
International explosion protection certificates, overfill prevention WHG, SIL, hygienic certificates, marine approvals
Benefits
Use also in safety systems requiring functional safety to SIL2 in accordance with IEC 61508Reliable and universal application thanks to wide range of certificates and approvals No calibration necessary (factory preconfiguration). No calibration necessary for media with a conductivity of 100μS/cm and higherMaterial in contact with the process made of corrosion-resistant materialMenu-guided local configuration via plain text display (optional) Two-stage overvoltage protection
