General Description
This Option Series provide strain gages with 'Modulus Compensation' features through use of specially modified lots of K alloy . The 'Mod-Comp' match will be quite close for the materials specified, although thermal output characteristics may not be ideal.

When force-responsive type transducers are manufactured from the metals listed, and the appropriate Special Option gages are used, the result is a transducer which demonstrates very little span change with temperature.
