Strain gauges are usually installed on a surface whether it is for stress analyses or sensor production,without any external force applied to the surface.When environmental temperature changes,the resistance of the strain gauge changes accordingly.This phenonmenon is called the strain gauges thermal output.This thermal output is the result of interactions and superposition of the resistance temperature coefficient of grid materials,the sensiitive grid materials and the linear expansion coefficient.
Common strain gauges often have a large thermal output . Thermal output is the biggest source of errors in static strain measurements,When temperature increases the dispersion and therefore the thermal output value increase.Ideally the thermal output of strain gauges should be zero.To meet this requirement a self-temperature compensating strain gauge is used.
y adjusting the composition ratio of the alloys of the strain gauge sensitivity grid material,and make used of cold rolling and proper heat treatment,the internal crystalline structure of gauge material can be altered in way it will compensate the changes of the material due to temperature change.This way the change in Thermal output can be kept very close to zero and standards for high-precision sensors and stress analysis can be met.
 The
configuration of the Sensitive Grids We select the configuration of
the Sensitive Grids according to the stress and other demands. Like
when the main stress is unknown or shear strain, then we can select
multi-axes strain gauge, we use these strain gauge which Triaxial
angle are *5°, *0° or **0° for the first situation; And use
Triaxial angle is *5° for another situation. If we test the know
stress strain, then we can select Uniaxial strain gauge; the circle
multi-axes strain gauge is used in Pressure
sensor.
Temp.
Self-compensation and Elastic Modulus self-compensation We should
select different Temp. Self-compensation or Elastic Modulus
self-compensation strain gauge according to its materials,
working Temp. and the precision. Like some common steel or spring
steel, then use Temp. Self-compensation strain gauge with the
*1×*0/ expansion coefficient; And to ºC the Aluminum alloy,
then use strain gauge with *3×*0/ expansion coefficient.
ºC
Creep
Grade The user should select the matching Creep Grade according
to the configuration, capacity and Elastomer of the load cell.
First time we can select one or two kind of different Creep
Grade's strain gauge to test, and according to the last test
data, and then select the best Creep Grade.
