Our bondable wire-wound strain gages have been the world’s premier high temperature strain gage for several generations.  HPI staff has been involved with the manufacturing of these gages since their inception in the early 1960’s.  Wire wound strain gages have many benefits including the ability to survive and test at temperatures above 2000⁰F (1094⁰C) and high fatigue life.  Custom strain gage and lead wire options are also available.
