Webinar: Applying the Wheatstone Bridge Circuit with Strain Gauges

 

This webinar has been recorded and was originally held on November 16th, 2017 at HBM in Darmstadt, Germany.

In 1843, the English physicist Sir Charles Wheatstone (1802-1875), found a bridge circuit for measuring electrical resistances. In this bridge circuit, known today as the Wheatstone bridge circuit, unknown resistances are compared with well-defined resistances. The wheatstone bridge is also well suited for the measurement of small changes of a resistance and is, therefore, also suitable for measuring the resistance change in a strain gauge.

In this 30-minute webinar, HBM product manager Dirk Eberlein, an expert in the field of strain gauges, guides you through the basics of the Wheatstone bridge curcuit:

  • Learn to distinguish the Wheatstone bridge circuit in quarter, half and full bridge circuits
  • Understand the applications of the quarter, half and full bridge circuits in measurements:
    • bending rod
    • traction / compression rod
    • torsion bar
  • Learn about the possibilities of temperature compensation by using the Wheatstone bridge circuit
