MAGNETOSTRICTIVE LEVEL TRANSMITTEROPERATING PRINCIPLEThe operating principle of magnetostrictive level gauges isbased on a physical property named “ W i e d e m a n n effect” .This technology allows the continuously reading of liquid levelwith very high accuracy. Our DIGIMAG level transmitter is mainlyconstituted by a microprocessor electronic circuit positioned ina n aluminium ex- proof box on the top of the stainless steeltube having in its internal part a waveguide fitted in the tank.A mechanical pulse caused by the magnetostrictive t w i s tstrain is generated in the exact meeting point with themagnetic field of the permanent magnet kept into floats.The mechanical pulse propagates into the waveguideat sound speed up to the sensor located in the measuringhead. The measurement of the time between the initial pulseand the back pulse exactly defines the position of the floats.MAIN FEATURESMicroprocessor electronic, no field calibration requiredPossibility to substitute internal sensor without removal waveguide from the tankPipe sensor in stainless steel AISI 304/316LMeasure range up to 6 metersProcess connections to tank: adjustable threaded connectionDigital outputs data for :- level of liquid in 0,1 mm- interface (water detection) in mm- temperatureP V C o r S p a n s i l FloatsP r o b e :- accuracy:± 0,5mm- resolution ± 0,1mmTemperature :- accuracy:± 0,2mm (ref. measuring range – 2 0 + 4 0 °C)- resolution ± 0,0625mmSupply voltage: 9 ÷ 30 Vdc < 3 0 m ASerial output RS 485Tele- diagnostic and Tele- maintenance by GSM / InternetAverage product temperature up to 10 digital sensorsExplosion proof ATEX CESI and INERIS - OIML R85(pending)CEComplianceOPERATING PRINCIPLEDIGIMAG XMTTEMPERATURE ERROR CURVEDIGIMAG XMT IP68
