THE
SELF-COMPENSATION OF STRAIN GUAGE
.
…ÂÂ
Temp. Self-compensation
The hypostasis
of Zero Output is the Potential Discrepancy of load cell between
two output
terminals, and
the Potential rest with the two Electric Bridges resistance. The
working Temp. of this
Electric
Bridges resistance change as well as the Zero Output of load
cell, so this change about the
Zero Output of
load cell called Zero Excursion(P).
Why the
Electric Bridges resistance will be change when the Temp. change?
To strain gauge, it is
affected by its
Heat Output. Heat Output is the strain gauge installed on the
unfettered specimen, no
force, when the
environmental Temp. Changes occur as a chance in its resistance.
So the ideal of strain
gauge is the
Heat Output approach Zero. This kind of strain gauge is Temp.
Self-Compensation Strain
Gauge. But it
is opposite speaking to Self-Compensation, this Temp.
Self-Compensation Strain Gauge
also have Heat
Output, just it is less than others.
We always
change the materials of Sensitive Grids and change the Resistance
Temp. Coefficients
by heat
treatment make to make the Heat Output of strain gauge to
approach Zero. We synthesize the
function
relations which among Elastomer linear expansion coefficient,
Foils linear expansion
coefficient,
Resistance Temp. Coefficient and Temperature, with suitable heat
treatment to produce
Self-Compensation strain
gauge which linear expansion coefficient is
9,*1,*6,*3.
Remark: *1 is
suit for alloy steel, Martensite stainless steel,
Precipitation
Hardening
stainless steel etc.. *6 is suit for Austenitic Stainless Steel
etc.. *3 is suit for
Aluminium alloy
etc...
…¡.Creep
Self-compensation
All metal will
bring spring aftereffect, it says when the metal have force in
its spring scope, it
distort and
will not balance with its load at once, but a little later; after
retract the force, it also will not
distort to
original state at once, but a little later, it will become the
same. So this will show by Positive
Creep that the
output signal of load cell increase as the time increase. The
output signal also will
Negative Creep, because the fundus and slice will slack (By
stated stress will decreased by time), and
the value can be adjusted by change the configuration of
Sensitive Grids, the materials of fundus and
produce technics. If the absolute value of Positive Creep is the
same as the Negative Creep, then the
Creep of the load cell can Self-compensate to the best. Our
company produces different Creep grade
strain gauge to satisfy our clients.
….Elastic
Modulus Self-compensation
In elastomer, elastic modulus decrease with the raise of the
ambient Temp., and the output of the
load cell increase with the raise of the Temp. We adjust the heat
treatment of Sensitive Grids to make
the Sensitive coefficient K decrease with the raise of the Temp.,
in order to counteract the increase
which brought by the elastic modulus decrease with the raise of
the Temp. at last to achieve
Self-compensation,this strain gauge is called Elastic Modulus
Self-compensation Strain Gauge. It
synthesize both effects about common strain gauge and
Self-compensation elastic modulus, good
stability, low cost, high sensitivity, easy to produce and work,
it is also suit for load cell which the
precision grade is 0.*5 or mass production and low cost.
