Benefits of Strain Gauge Measurement
There are large numbers of devices available in the market that are specifically used to measure strain. The reason behind the use of such instruments is to ensure utmost productivity and safety. Ther...
If you see, you will come to know that everything around us is running on the concept of mechanics and a single error or mistake can leads to serious complications. For example, a plane carrying 500 passengers is considered to be very important as any kind of issue with any devices in the plane can cause unrecoverable losses. Therefore engineers do strain gauge measurement to bring in the sense of security and safety.
Another example is a powerhouse which provides electricity to thousands of homes and industries. Any issue with turbine can cause power loss for several hours. Therefore, it is extremely important to ensure proper strain gauge measurement. The stresses imposed by head and movement upon the material components of all the machines that power our lives do not in themselves cause break downs but are the causes that will inevitably result in effects.
A strain gauge is generally comprises of a resistance-based sensor used by mechanical engineers. Strain does not formally have a unit of measurement, but for reference objectives, a special unit of measurement is used. Because the changes in length are generally very small, the unit of change employed is expressed as 10 to the power of six, to provide eloquent readings.
There are different kinds of sensor with varied configurations. The metal foil gauge consists of a length of thin metal wire wound around a grid called a matrix. This is attached to a metal backing and then stuck to the object where measurement is required. The gauge is aligned with the line in which stress will emerge. As the wire lengthens or compresses, so measurements are read.
Configurations of gauges can be customized to measure different strains that might apply to objects of various sizes and components. For example the bi-axial configuration can measure along different planes, as in a hole or cutting instrument. Here two different appliances are aligned at right angles to a common point in a bid to measure along different axes.
