What is a Strain Gauge Used For?
A strain gauge is an electrical sensor used to measure changes in force or strain (hence their name). The resistance of a strain gauge varies when force is applied.
Pressure, force, weight, tension etc can be converted into a change in electrical resistance which can be easily measured.
Stress and Strain are the result of external forces being applied to a stationary object. The objects internal resisting force is known as Stress. Strain is the displacement and/or deformation which occur to the object; this is what a strain gauge will measure. Strain gauges are able to measure either contraction or expansion of an area or object.
What Causes strain?
Strain is anything external to the object which may cause displacement, some examples are;
· Structural changes
· Other movements
These external movements will cause an object to react in some way. A strain gauge will be able to measure the reaction.
What are strain gauges used for?
So, what is a strain gauge used for? Strain gauge technology has almost unlimited uses in the field. Strain gauges are often use in the following industries:
· Mechanical Engineering
· Research and Development
Because they are so versatile strain gauges are used for many different applications some examples are;
· Testing ships hulls
· Structural components for bridges and buildings to measure stress and ensure it is not dangerous
· Vehicle testing applications
· Stresses on wing deflection on aircrafts
· Stress on railway lines
· Rotational strain and speed on motors, turbines, fans, wheels and propellers
In all cases the strain gauge can measure the strain on the object and an alert will be triggered to inform personnel when a component has reached capacity so that the problem can be solved before the situation becomes dangerous.
