The　elasto-magnetic　method　is　a　promising　pathway　for　cable　force　monitoring　in　cable-stayed　bridges.　Under　the　action　of　an　externally　applied　pulsed　magnetic　field,　both　the　variation　in　the　main　flux　recorded　by　the　induction　coil　and　the　localized　surface　magnetic　field　measured　by　the　packaged　magnetic　sensor　are　typical　signals　for　observing　the　elasto-magnetic　effect　in　tensioned　cables.　However,　the　performances　of　the　parameters　extracted　from　the　two　types　of　elasto-magnetic　signals　are　never　strictly　compared　in　the　experiment.　Meanwhile,　comprehensive　indicators　for　evaluating　the　ability　of　elasto-magnetic　parameters　on　cable　force　characterization　are　seldom　discussed.　As　a　result,　it　is　difficult　to　compare　the　performances　of　elasto-magnetic　devices　developed　by　different　teams,　and　the　pathway　of　seeking　new　parameters　for　cable　force　monitoring　is　obstructed.　In　this　study,　elasto-magnetic　calibration　experiments　were　performed　on　a　cable　of　seven-wire　steel　strands　to　simultaneously　measure　the　variation　in　the　main　flux　and　the　localized　surface　magnetic　field.　Comprehensive　indicators　considering　sensitivity,　hysteresis　error,　and　cable　force　resolution　are　proposed　to　examine　the　performances　of　classic　elasto-magnetic　parameters　and　new　candidate　ones.　Through　comparative　study,　two　new　parameters　demonstrated　outstanding　ability　for　cable　force　measurement,　and　they　are　the　minimum　amplitude　of　the　induced　voltage　and　the　area　under　the　curve　between　two　points　of　3　dB　height　of　the　voltage　measured　by　a　Hall　sensor.　The　latter　is　recommended　for　high-performance　cable　force　monitoring　from　the　perspective　of　simplicity　in　sensor　configuration.
