Convert strain gauge readings to stress

WebA strain gauge, or strain gage, is a type of sensor device. It measures stress and fatigue forces in materials it is directly attached to using the properties of electrical conductance. All Strain Gauges. Strain gauges and load cells are types of transducers, meaning they convert one form of energy into another. WebA strain gage torque transducer is designed using the above relational expression of ε 0 and T. Obtain ε 0 from the allowable stress for the material, and determine the width d of the axis which is matched with the …
