Strain Gauges

Strain gauges are devices used to measure strain. A strain gauge is a device that is constructed with an elastic material which is bonded to a backing which is bonded to a device for measurement. Strain gauges measure the strain along the gauge length as a fraction of the length of the gauge. The most common type of strain gauge is the MMF003152, which has an application field and working principle.

Application Field

The MMF003152 strain gauges are designed for measuring and controlling the shape and magnitude of tension, compression, and torque forces and their effects on a variety of materials including metals, plastics, composites, and ceramics. They are commonly used in research, engineering, and industrial applications to measure the effect of force and pressure on various materials. Examples include measurement of tensile test specimens, fatigue tests, welding tests, and construction of pressure vessels.

Working Principle

The MMF003152 strain gauge is made with a ceramic-bonded backing and a flexural mounting base. It consists of a circular disk of ceramic-bonded material that has been bonded to a rigid backing. The flexural mounting base serves as the reference point for the gauge and allows for bending and expansion. The strain gauges are designed so that when a force is applied, the disk will bend and expand in the direction of the force, thereby changing its dimensions. This change in dimensions is measured as a fraction of the original length of the disk.

The flexural mounting base is connected to an amplifier, which converts the small electrical signals generated by the ceramic disk into larger signals. The larger signal is then sent to a meter or a digital readout, which displays the level of strain on the disk. This information can then be used to measure the strain forces on a variety of materials.

Conclusion

The MMF003152 strain gauge is a reliable and accurate instrument used to measure strain and deformation. It is useful for research and engineering applications, as well as industrial applications. Its ceramic-bonded backing and flexural mounting base allows for bendable and expandable measurement. The amplifier and digital readout are used to accurately measure strain forces on a variety of materials.
