KFHB Series
High-temperature Foil Strain Gages (250ºC)

Summary

The base is made of highly heat-resistant polyimide and the gage element is made of NiCr alloy foil, thereby ensuring less thermal output and excellent temperature characteristics.

Relative images

When ordering, suffix the lead-wire cable code to the model number with a space in between.

E.g.
KFHB-5-120-C1-11 with a fluoroplastic-coated high/low-temp. 3-wire cable 5 m long pre-attached.
→ KFHB-5-120-C1-11 A5M3

If no lead-wire cable code is suffixed, the gage is delivered with an advance ribbon cable only (25 mm long).
