Electrical Resistance Strain Gauge Apparatus

Product Description

Descriptions of DIDACElectrical Resistance Strain Gauge ApparatusThe Electrical Resistance Strain GaugeApparatushas been designed to illustrate 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, and an identical gauge is fixed to an unstressed piece of the same material for temperature compensation. The two gauges form part of a wheatstone bridge which has a balancing potentiometer, and whose meter is calibrated directly in microstrains. The cantilever is loaded by the load hanger and calibrated weights hung from its free end. A torsion bar is also supplied having two gauges bonded orthogonally at 45. A detailed label on the unit shows the wheatstone bridge arrangement and how the specimen strain gauges connect into the circuit.Experimental Capabilities of Electrical Resistance Strain GaugeApparatus To show the application of Electrical Resistance Strain GaugeApparatusin the measurement of stress due to bending and torsion To demonstrate the use of wheatstone bridge arrangements in measuring change of resistance Visibly shows location of Electrical Resistance Strain GaugeApparatuswithin wheatstone bridge arrangement and the position and use of balancing potentiometers With optional extras to show other methods of temperature compensation in conjunction with tension and compression specimens Dummy, temperature compensation gauges Wiring of Electrical Resistance Strain GaugeApparatus Specifications of Electrical Resistance Strain GaugeApparatusThe apparatus has been designed to illustrate the basic features of electrical resistance Electrical Resistance Strain GaugeApparatusand their application in measuring bending and torsion.
