The 8281B 0091000 is a piece of equipment used in a variety of industrial applications, from automotive and aerospace to semiconductor and medical device manufacturing. It is designed to measure the response of a structure or system to dynamic loading, and can be used in static, dynamic, and fatigue tests. This article will explore the application field and working principle of the 8281B 0091000.

Application Field

The 8281B 0091000 is designed specifically for fatigue tests. It is unique in that it can measure strain levels in two different directions, allowing for dynamic and rotating strain tests. It is also capable of taking strain readings on different surfaces such as metal, plastic, and composite materials. 

It is most often used in automotive and aerospace applications, where it is used to test the fatigue strength of parts under cyclic loading. In vehicle construction, the 8281B is used to examine the fatigue strength of components like springs, tie rods, and cross-members. In the aerospace industry, it is used to test the fatigue strength of various parts of aircraft and helicopters.

It is also used in semiconductor and medical device manufacturing, where it can measure the response of a device or system to dynamic stress. In semiconductor manufacturing, it is used to measure the strain in thin-film transistors, ICs, flat-panel displays, and other components. In medical device manufacturing, it is used to measure the strain in implants and other medical devices.

Working Principle

The 8281B 0091000 measures the strain in two different directions, using two different types of transducers. A strain gauge transducer is used to measure longitudinal and transverse strain, while an accelerometer transducer is used to measure rotational strain. 

The strain gauge transducer consists of a strain gauge element bonded to the surface of the material being tested. When strain is applied to the test material, the strain gauge measures the resistance of the material. The measured resistance is then converted to a voltage signal, which is sent to the 8281B. The 8281B then uses this voltage signal to calculate the strain.

The accelerometer transducer consists of an accelerometer element mounted on the surface of the material being tested. When strain is applied to the test material, the accelerometer measures the acceleration due to the applied strain. This acceleration is then converted to a voltage signal, which is sent to the 8281B. The 8281B then uses this voltage signal to calculate the strain.

The 8281B 0091000 measures both static and dynamic strain. In a static strain test, the strain is applied and measured in one direction. In a dynamic strain test, the strain is applied and measured in two or more directions. The 8281B is capable of accurately measuring strain in both static and dynamic tests.

Conclusion

The 8281B 0091000 is a versatile and accurate device used in a variety of industrial applications. It is designed to measure the response of a structure or system to dynamic loading, and can be used in static, dynamic, and fatigue tests. It is most often used in automotive and aerospace applications, where it is used to test the fatigue strength of parts under cyclic loading. It is also used in semiconductor and medical device manufacturing, where it can measure the response of a device or system to dynamic stress.
