Piezo-Metrics’ strain gages fall in the ‘Discrete silicon gage’ category. (see tables) The semiconductor strain gages are micromachined from a wafer cut from a solid single crystal of “P” doped silicon. This manufacturing process minimizes the number of molecular dislocations and results in a strain-sensitive resistive device that is capable of accurately measuring high levels of strain. Besides the characteristics listed in the ‘Discrete silicon gage’ category in Table 1, Piezo-Metrics semiconductor strain gages also have the following attributes:
