Level displayed proportional to volume or height Parallel measurement of interface layer and overall Level possible via HART interfaceOptions Customised solutions Process connection, guide tube material and float from special steel, titanium, Hastelloy (others on request) In combination with limit switch, stepless setting of the limit values over the entire measuring rangeIllustration of the principleDesign and operating principle The measuring process is triggered by a current impulse. This current produces a circular magnetic field (3) along a wire (1) made of magnetostrictive material fixed in the guide tube. At the point being measured (liquid Level ) there is a float with permanent magnets (4) acting as a position transducer.

3 The interaction of both magnetic fields generates a mechanical torsion wave (5) in the wire. This is converted into an electrical signal at the end of the wire in the sensor housing (2) by a piezoceramic converter. The measured propagation delay enables the origination point, and thus the float position, to be determined with high Wire2 sensor housing3 Magnetic field4 Permanent magnet5 Torsional waveKSR data sheet LM 09/2015 Page 3 of 9 Product overviewSensor modelAproval (Option)withoutEx iEx d3 AFFG-PxxxFFG-TxxFLM-HxxSensor modelDescriptionMaterialsTemperature range(process)Stainless steel (316Ti)Stainless steel (316L)Titanium (grade 2)Stainless steel (316L)PPPVDFFFG-PMagnetostrictive sensor , standardxxx-60 .. +185 CFFG-TMagnetostrictive sensor , high temperaturexxx-90 .. +400 CFFG-TPMagnetostrictive sensor , plasticxx-10 .. +100 CFLM-HMagnetostrictive sensor , sterile versionxx-40 .. +400 CType approvalApprovalModelApproval N RU Sanitary Standards 74-06Ex approvalsExplosion protectionIgnition protec-tion typeModelZoneApproval numberATEXEx iFFG-T-Ex iZone 0 IBExU 02 ATEX 1124 X II 1/2G Ex ia IIC T3.
