KFU Series
High-temperature Foil Strain Gages (350ºC)
Summary
The base is made of highly heat-resistant polyimide and the gage element is made of NiCr alloy foil, thereby letting the KFU series gage exhibit superior characteristics over a wide temperature range.
Operating time (Depends on usage conditions)
24 hours or less at 350°C
72 hours or less at 300°C

Contents
When ordering, suffix the lead-wire cable code to the model number with a space in between.
E.g.
KFU-5-120-C1-11 with a high-temperature 3-wire cable 5 m long pre-attached
→ KFU-5-120-C1-11 E5M3
If no lead-wire cable code is suffixed, the gage is delivered with an advance ribbon cable only (25 mm long).
