Papers by Keyword: Magnetostrictive Delay Line

Abstract: The implementation of magnetostrictive delay lines in distribution measurement of temperature is presented in this paper. The sensing method and measurements as well as the proper selection and treatment of the amorphous sensing core are discussed.

Abstract: In this paper a cordless position sensor based on the Magnetostrictive Delay Line principle is presented. The working principle and the response of the sensor to coaxial and parallel moving magnetic field are analyzed. The output is selected to be the differential voltage of pairs of successive search coils. The measurements suggest monotonic dependence of the output of the sensor with respect to the permanent magnet’s position.

Abstract: Paper presents a novel application of magnetostrictive delay lines, which give a possibility of real time monitoring of strain in ceramic components. Magnetostrictive delay line was based on highly magnetostrictive Fe-Si-B amorphous alloy ribbon, mounted outside of ceramic component, what is a new solution for increasing sensor’s sensitivity. Developed specially for this sensor, hybrid digital-analog signal processing unit covers the sample-and-hold integrated circuit. The achived sensitivity and repeatability of the sensor confirms, that such solution is suitable for ceramic machine tool monitoring.
