Strain Gauge

Model deformation sensor

Library

Sensors

Description

The Strain Gauge block represents a sensor that generates a change in resistance as a function of strain using the following equation:

ΔRR=Kε

where:

  • ΔR/R is the fractional change in resistance.

  • ε is the strain at port E.

  • K is the Gauge factor parameter value.

Parameters

Gauge resistance

The unstressed gauge resistance. The default value is 100 Ω.

Gauge factor

The ratio K of the fractional change in resistance to the fractional change in length. The default value is 2.

Ports

The block has the following ports:

E

Strain input

+

Positive electrical port

-

Negative electrical port
