CF Series
Cryogenic Temperature Use

This epoxy-backed foil gage is designed for measuring under cryogenic conditions. The specially selected and heat-treated sensing foil shows very small zero shift under cryogenic temperature compared with conventional gage.

Main Test Materials Metal,Ceramic Materials Backing Epoxy
Operating Temperature -196 to +80°C Materials Element Special alloy foil
Compensation range -196 to +80°C Strain limit 1%
(10000×10-6)
Bonding adhesive EA-2
CN,C-1		 Fatigue life at room temp. 1×106
(±1500×10-6)
