Strain Gauge Calibration Apparatus- Engineering Lab Training Systems.
Technical Description
In a straight forward manner strain
gauges provide reliable information on the distribution, direction and
magnitude of mechanical deformation in components under load. Sufficient
knowledge of this measuring technology is vital in mechanical
engineering. This calibration device makes it possible for the user to
become familiar with the key features of strain gauge technology using a
prepared bending bar. The deformation of the bar under load is measured
by a mechanical dial gauge and at the same time by a strain gauge in a
full bridge configuration. By comparing the two results and appropriate
correction, the k-factor of the strain gauge is obtained as a key
characteristic. A voltage source and a measuring instrument are required
for the strain gauge.
