Even in measurements that are affected by temperature, you can compensate for temperature
by using a self-temperature-compensated strain gage. Longer wires are more susceptible
to the effects of temperature. Long wiring runs make lead wires susceptible to the effects of
temperature. You can make measurements with a high degree of precision by using wireless
modules to shorten wiring lengths.
For information about self temperature-compensated strain gages, contact your strain gage's
manufacturer.
