Self-Temperature-Compensation
|
The self-temperature-compensation feature of
Micro-Measurements strain gages with
A
and
K
alloys minimizes the effects of temperature changes
on strain measurements. The test material, operating
temperature range, and accuracy requirements dictate
the best self-temperature-compensation number for
each application. Micro-Measurements gages are
available for use on a wide range of materials.
The STC number (
SS
) is the approximate thermal expansion coefficient of
the structural material in ppm/deg F. The 06 (steels)
and 13 (aluminum alloys) values are most commonly
used, but values from 00, 03, 05, 06, 09, 13, 15, 18,
30, 40, and 50 are available. |
