Manetostrictive level gauge

Manetostrictive levelgauge supplies information on tank levels. Through its continuous filling level measurement it creates quality assurance and safety during the process. TORRIX is suitable for all liquid media for which a highly accurate level measurement is required.Advantages of TORRIX's Technology*Measuring accuracy up to 0.2mm*Resolution better 0.1mm*Simultaneous separating layer and filling level measurement possible*uController regulated*Temperature-compensated measuring principle*2-wire terminal(4-20mA)*HART Protocol*Very short measuring intervals*Application in ex-zone O (ATEX, IECEx certificate)*Durability due to robust structure*Shock and vibration-proof*Measuring range along the complete probe length freely adjustable*Very simple installation and startingFunctionThe sensor operates according to the magnetostrictive measuring process.A wire of magnetostrictive material is integrated into the probe tube.By means of the micro-controlled sensor electronics electrical impulses are sent through the wire creating a circular magnetic field.A magnet is built into the float which magnetizes the wire at the float position of the two magnetic fields a torsion wave is generated which spreads along the wire to the sensor head.The propagation time is registered and processed by the electronics.DesignTORRIX consists of:Stainless steel transducer housing(304)Stainless steel probe tube(316Ti);Hastelloy c;other upon requestScrew-in unit (height adjustable) (Stainless steel 316Ti;brass);flange (probe tube welded) (stainless steel 316Ti;Hastelloy plated)Stainless steel product float (316Ti); Titanium;Hastelloy CAccessories*Transducer analysis e.g. UM-X*eX-LSOLATING AMPLIFIERInstallation instructionWhen installing the sensor in the ex-range please make sure that the sensor is fed with an approved ex-pover supply.Housing:Protection type: IP 68 (optional with ventilation screw)Measurements:50*120mmMaterial: Stainless steelCable diameter:5...10mmProbe Tube:Diameter:12mmMaterial: Stainless steel 316 Ti;Hastelloy CLength:200...4000mmProcess connection:*Screw-in unit for height adjustable mounting R1 1/2 Brass G 1/2 Stainless steel 316 TiG 1/2 Stainless steel 316*welded standard flangesMeasuring Accuracy:*filling level:up to 0.2mm*Resolution:up to 0.1mm*Analogue part: 0.1%/KResolution better 0.5 uATemperature Range:*Medium: Standard temperature:-40...+125 centigrade high temperature -40...+250 centigrade highest temperature:-40...450 centigrade lowest temperature:-65...+125 centigrade*sensor head:-40...85 centigradeElectrical Data:Connection:2-wireSupply:10...30 VDCCurrent signal:4...20mAError message: adjustable to 3.6 or 21.5 mAHart-protocol Version 6.0Function of the measuring transducer TORRIXThe method of measurement illustrated in the drawing exploits the physical effect of magnetostriction and is largely independent of temperature. inside the probe tube there is a tense wire made of magnetostrictive material. The sensor circuitry emits pulses of current through the wire, Thus generating a circular magnetic field. The level transmitter is magnet, which is integrated into the float. Its magnetic field magnetises the wire axially. Since the two magnetic fields are superimposed. around the float magnet a torsion wave is generated which rus in both directions along the wire. One wave runs directly to the probe head whilst the other is reflected at the bottom of the probe tube. The time is measured between emission of the current pulse and arrival of the wave at the probe head. The position of the float is determined on the basis of the transittimes.
