Instruments and Systems: Monitoring, Control, and Diagnostics Annotation << Back Calibration system for magnetostrictive linear movement transducers B.H. YASOVEEV, R.U. MUKAEV, A.A. SHMEVEL The paper presents calibration system for magnetostrictive linear movement transducers. Relevancy of magnetostrictive linear movement transducer application in automated control systems operating in a real-time mode is stated. A method of processing of data signal coming from a primary magnetostrictive linear movement transducer having higher resolution capability and self-calibration is considered. The paper notes that it is theoretically difficult to take into account influence of errors on measurement results and therefore a method of magnetostrictive movement transducer calibration for the purpose of further error correction is offered. A calibration circuit for a magnetostrictive movement transducer is proposed and calibration algorithm is developed. An example of identifier position computation by determination of identifier intensity center is demonstrated. The paper presents a table and plots of resolution ratio of calibration system against length covered with a digital microscope and against array resolution value of a digital microscope. The magnetostrictive movement transducer calibration system provides resolution of 0,0001 mm. Key words: magnetostrictive linear movement transducer, calibration, linear position detector, metrology, digital camera/microscope. Contacts: E-mail: sasha_sh_88@mail.ru Pp. 55-61.
