Strain Measurement
Errors

Page 1 of 7
A Micro-Measurements strain gage is an inherently
precise measurement device easily capable of
resolving one part in a million or more. That
capability is primarily due to the exacting standards
and controls under which every strain gage is
manufactured. Yet, the titles of many Vishay
Measurements Group technical publications make
reference to errors. These numerous references should
not, however, be viewed as a lack of confidence in
the intrinsic accuracy of the strain gage itself. The
principal errors cited in these publications arise
from the way in which the strain gage is installed
and the strain measurement made by the user. Indeed,
these publications are made available to our strain
gage customers because we believe that only by
thoroughly understanding the error sources associated
with the use of a measurement device can the user
hope to achieve optimal measurement accuracy.
