The Strain Gauge block represents a sensor that generates a change in resistance as a function of strain using the following equation:
ΔR/R is the fractional change in resistance.
is the strain at port E.
K is the Gauge factor parameter value.
E— Strain input
Physical signal port associated with the strain input.
+— Positive port
Electrical conserving port associated with the strain gauge positive port.
-— Negative port
Electrical conserving port associated with the strain gauge negative port.
Gauge resistance— Unstressed gauge resistance
Unstressed gauge resistance.
Gauge factor— Gauge factor
The ratio K of the fractional change in resistance to the fractional change in length.
