The　magnetic　measurement　stress　sensor　is　the　core　of　the　magnetic　measurement　stress　technology.　Magnetic　measurement　stress　sensor　using　magnetostriction　and　Giant　Magneto　Resistance　(GMR)　theory　has　good　correspondence　between　stress　and　magnetic,　and　been　validated　scientific　and　reliable　through　indoor　experiments　and　engineering　applications.　This　paper　gives　a　method　on　stress　sensor　anode　calibration,　verifies　the　different　performance　of　the　sensor　based　on　different　materials,　makes　an　analysis　of　the　error　between　the　theoretical　calculations　and　actual　measurements　of　the　standard　objects,　describes　the　working　conditions　of　using　the　sensor　and　indicates　a　reasonable　match　is　a　prerequisite　to　obtain　the　desired　signal　processing　results.　©　(2013)　Trans　Tech　Publications,　Switzerland.
