Strain gauges are sensing instruments that measure the strain (deformation) within an object. The MMF000939 strain gauge is one of the more commonly used strain gauges within the industry. In this article, we will explore its application field and working principle to better understand how strain gauges work.

Application Field

The MMF000939 strain gauge is a general-purpose strain gauge that is used for many different applications. It is designed to accurately measure objects that experience slight to moderate levels of strain. Examples of objects that would benefit from the MMF000939 strain gauge include automotive components such as suspension arms, aerospace components such as wings and fuselages, and medical devices such as prosthetics and implants.

This strain gauge is also used in the construction industry when fabricating reinforced concrete structures, designing and measuring the stress performance of bridges, or monitoring stress levels in structural columns and support beams. It is useful for measuring strain near large structural welds, as well as cracks that may develop in these structures.

The MMF000939 strain gauge can also be used in mechanical engineering applications, such as testing the tolerance of machinery components and measuring the tension in shafts and gears.

Working Principle

Like other strain gauges, the MMF000939 strain gauge works on the principle of resistance change. When an object is subjected to strain, the resistance of the strain gauge changes according to the amount of strain in the object. The strain gauges consist of a thin metal foil pattern that is mounted onto an insulating base. The metal foil is bent when the object is subjected to strain, and this change in shape results in a change in the electrical resistance.

This strain gauge is designed so that the resistance change occurs in proportion to the amount of strain in the object. The resistance value is then used to calculate the amount of strain in the object. The strain gauges can be connected to sensors that measure the changes in resistance, which are then recorded and analyzed to produce data on the strain levels.

The MMF000939 strain gauge is also designed with features like temperature compensation. This feature ensures that the strain gauge is accurate even when the temperature of the object changes, as the resistance of the metal foil alters with temperature.

Conclusion

The MMF000939 strain gauge is a popular strain gauge that is used in a variety of applications, from automotive components and aerospace components to structural columns and reinforced concrete construction projects. This strain gauge works on the principle of resistance change, and its features and design enable it to accurately measure strain levels in objects. The data collected by the strain gauge can then be used to calculate the amount of strain in the object.
