Introduction to Strain Gauges

A strain gauge is a transducer which converts a mechanical strain into an electrical signal. Its application in the field of mechanical engineering is crucial for accurately measuring strain in materials and structures. This article will discuss the MMF000911 strain gauge, its application field, and provide an explanation of its working principle.

Applications of the MMF000911 Strain Gauge

The MMF000911 strain gauge is a convenient and reliable tool for accurately measuring strain in materials and structures. This particular strain gauge is designed to withstand temperatures up to 125°C (257°F), making it well-suited for environments where high temperatures are common. It is also designed to exhibit very low creep, meaning that it will not shift its output signal when subjected to long-term strain. The MMF000911 also features a flexible and adaptive design, capable of being used with both thin and thick materials.

The most common applications of the strain gauge are in the field of aerospace engineering and automotive engineering. In aerospace engineering, strain gauges are used to measure stress, strain, and load on aircraft components and structures, allowing engineers to assess the stress capacity of a particular component. The MMF000911 strain gauge is also frequently used in automotive engineering for measuring the loads and strains on engine components such as pistons, crankshafts, and valves.

Working Principle of the MMF000911 Strain Gauge

The MMF000911 strain gauge is designed to measure strain using the mutual magnetic induction principle. In this way, the strain gauge operates on two independent electrical circuits. The first circuit is the circuit in which the strain gauge is attached, and the second circuit is connected to the points of application and is located outside the gauge. When the first circuit is subjected to strain, the strain causes a change in the resistance of the wire in the gauge. This change in resistance causes the output voltage of the first circuit to fluctuate, which is then transmitted to the output terminals of the second circuit.

The output voltage of the second circuit is proportional to the strain in the wire of the first circuit, and therefore allows engineers to determine the amount of strain on a particular component. For example, by measuring the output voltage and comparing it to a known calibration value, an engineer could determine the strain on an engine component such as a crankshaft.

Conclusion

The MMF000911 strain gauge is a highly reliable and accurate strain gauge designed for use in a range of applications. It is suitable for use in temperatures up to 125°C (257°F) and exhibits very low creep, making it ideal for long-term strain measurement. Furthermore, the MMF000911 operates on the principle of mutual magnetic induction and is capable of providing accurate strain measurements that are proportional to the strain in the wire of the first circuit.
