About the CFRA Series Cryogenic Low Temperature Straingauges

CF series cryogenic temperature strain gaige
These are foil strain gauges with epoxy backing designed for measurement under cryogenic conditions. They are available in single element, rectangular 2-element and rectangular 3-element configurations with 350Ω resistance. The specially selected and heat treated grid of the gauges shows very small zero shift under cryogenic temperature compared to conventional strain gauges.

Temperature compensation materials

11: Mild steel
17: Stainless steel
23: Aluminium
