Strain gauges are transducers, which can convert mechanical forces or strains into electrical signals. The MMF311981 strain gauges are considered to be one of the most popular strain gauges used in measuring mechanical tension, pressure, and forces. Their working principles and application fields are discussed in this article.

The MMF311981 strain gauges is a type of medal foil strain gauge. It is made up of a thin, metallic electrical resistance wire or a semiconductor trace that is built on a flattened foil and adhered to a plastic backing. The foil is etched to create a pattern that increases the gauge’s sensitivity to strain, and this allows it to convert a small change in length or shape into a measurable electrical resistance. These strain gauges are designed to measure tension, pressure, and forces. They are used for measuring vertical or lateral loads.

The working principle of the MMF311981 strain gauges is the same as other strain gauges. When the material to which the strain gauge is bonded is subject to strain, it also stretches the electrical trace. When the strain increases, the electrical resistance of the trace increases and when the strain decreases, the electrical resistance of the trace decreases. This change in resistance in the trace is measured by a Wheatstone bridge and converted to output voltage.

The application fields of MMF311981 strain gauge are numerous. It can be used for measuring tensile, compressive or flexural forces. Due to its small size, it is often used in aerospace applications such as measuring the load on wings and control surfaces. It can also be used in automobile and mechanical engineering applications such as measuring forces in engines and other mechanical components. The MMF311981 strain gauges is also used in civil engineering applications where it can be used to measure active earth pressures, foundation settlement, and other structural deformations. It is also used in medical and biomedical engineering applications where it can be used for measuring force on body parts and assessing conditions such as ischemia.

In summary, the MMF311981 strain gauges is a popular transducer that can be used to accurately measure tension, pressure, and forces. It works by converting the strain in the material to which it is bonded to changes in electrical resistance. They are used in aerospace, automotive, mechanical, civil engineering, and medical applications.
