KSPB
Semiconductor Strain Gages
The KSPB series gages are stable-performance semiconductor strain gages usable for general stress measurement and transducers. The F2 type has a half-bridge formed with a 2-element structure (Positive and Negative), for self-temperature compensation and is suitable for strain measurement of steel products.
