Strain Gage

Strain gages are sensors that detect slight mechanical dimension changes (strain) as electrical signals. Kyowa manufactures strain gages suitable for a wide variety of measurement environments, including environments from high to extremely low temperatures, and environments underwater or in hydrogen gas.

Types of Strain Gages

There are several types of strain gages, such as foil strain gages, wire strain gages, and semiconductor strain gages. Features vary by type, and certain strain gages are best used for specific measuring targets and in certain environments.

Kyowa's Typical General-purpose Foil Strain Gages – KFGS Series

Kyowa's typical strain gages are KFGS series. Each strain gage in KFGS series features an outstanding moisture resistance and exhibits the power in field measurement too. Unless any waterdrop is splashed on it, no coating is required. Thus, KFGS strain gages can be used for various purposes.
