Determining the gauge factor of strain gauges

As universal aids to experimental stress and strain analysis, strain gauges enable mechanical strain to be converted into electrical signals. The signal obtained is processed by a strain measuring amplifier to give a display of the resulting strain.

• investigation of deflection and strain to determine gauge factor
• bending bar with 2 strain gauges on the compression side and tension side respectively
• strain gauge configured as full bridge
• 2-point ball bearing mounting of bar permits purely bending load application
• mechanical load application device with spindle, handwheel and cross-arm
• dial gauge with adjustable dial for direct measurement of deflection
• measuring amplifier with 4-digit digital display
