Bonded-wire strain gauges - Research Paper Example

investigation discovered that alloys of small wires could be used to measure surface strain of a wire (Potma 78). The improvement was also realized in 1952 when Saunders-Roe Company from the UK, this company succeeded in developing a strain gauge by way of etching the gauge pattern using a thin foil (Yarnell 82), this development accounts for the different strain gauges that are used today for the various purposes. Who Invented the Sensor? On who invented the strain gauge sensors, it will be acknowledged Lord Kelvin, this is given the fact that it is from his thought that subsequent knowledge has stemmed. He realized the relationship that exists between the strain and the resistance of different wires in1856 (Yarnell 82). How and where is it Currently Used in Industry? The strain gauges are mostly used in measuring the level of stresses that is generated by machinery. With this type of relationship, it is mostly used in the mechanical engineering where stresses generated have to be ascertained for research or development issues. One of the industries that use the technology frequently is the aircraft, several components of the craft have to be tested for various stress level for safety purposes. An example of the gauge is shown below Theory behind Sensor/ How It Works With the assistance of the adhesive material that is used in the strain gauge, it is usually pasted on the structure is to be tested for study. When the structure is subjected to some extent of force, compressive or tensile, it will have to be altered in terms of dimension. Because they are bonded together with the structure, the structure will equally undergo the same level of alteration as the testes material. This strain also changes the resistance capacity of the strain gauge, which is then ascertained using the wheat stone bridge (Potma 84). The adjustment that is experienced in the resistance of the strain gaug
