Webinar: Applying the Wheatstone Bridge Circuit with Strain Gauges

 

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
