ELECTRICAL RESISTANCE STRAIN GAUGE

This apparatus illustrates the basic features of electrical resistance strain gauges and their application in measuring bending and torsion. A cantilever has a single gauge bonded onto its surface, with an identical gauge fixed to an unstressed piece of the same material for temperature compensation. The two gauges form part of a Wheatstone bridge with a balancing potentiometer, whose meter is calibrated directly in microstrains.

A torsion bar is also supplied with two gauges bonded orthogonally at 45°. Learn about ELECTRICAL RESISTANCE STRAIN GAUGE for educational labs for optimal educational outcomes.. A detailed label on the unit shows the Wheatstone bridge arrangement and how the specimen strain gauges connect into the circuit.
