A　magnetization　method　using　superimposed　high-　and　low-frequency　magnetic　field　was　proposed　to　simultaneously　achieve　elasto-magnetic　tensile　stress　measurement　and　ultrasonic　guided　waves　inspection　in　steel　strands.　Two　versions　of　experimental　set-ups　were　constructed　based　on　two　types　of　amplifiers.　In　the　experimental　set-up　using　KH7500　amplifier,　the　high　frequency　component　of　the　output　signal　of　the　integrated　sensor　represented　magnetostrictive-based　ultrasonic　guided　waves,　and　the　low　frequency　component　carried　the　information　of　minor　hysteresis　loop.　In　the　experimental　set-up　using　BMP-360T　amplifier,　the　sensor　employed　two　individual　sensing　coils　to　detect　the　signals　of　minor　hysteresis　loop　and　ultrasonic　guided　waves,　respectively.　The　experimental　results　obtained　from　the　two　versions　of　experimental　set-ups　show　that　there　is　a　good　linear　relationship　between　the　peak　value　of　the　low　frequency　induced　voltage　and　the　tensile　stress.　The　research　outcomes　provide　technique　for　simultaneously　conducting　elasto-magnetic　tensile　stress　measurement　and　ultrasonic　guided　waves　inspection　in　steel　strands.　©　2019,　Editorial　Department　of　Journal　of　Beijing　University　of　Technology.　All　right　reserved.
