In summary, a torsional strain gauge is a sensor used to measure torque applied to an object. It works by converting torque into an electrical signal through a strain-sensitive element. Torsional strain gauges have various applications in industries such as automotive and aerospace, and factors to consider when purchasing one include measurement range, accuracy, and compatibility. To choose the right gauge, it is important to evaluate technical specifications and consult with a specialist or manufacturer.

I don't think there is sich a thing as a "torsional strain gauge". Strain gauges measure direct strain. If you have torsion in a circular shaft for example, there is a shear strain on the surface of the shaft which is equivalent to equal and opposite direct strains at 45 degrees to the axis of the shaft. So you just use two "ordinary" strain gauges at 45 degrees to the axis.

A strain gauge rosette with 3 gauges 120 degrees apart will measure any two-diimensional strain field.
 

What is a torsional strain gauge?

A torsional strain gauge is a type of sensor used to measure the twisting or rotational force, also known as torque, applied to an object.

How does a torsional strain gauge work?

A torsional strain gauge works by converting the applied torque into an electrical signal. This is achieved through the use of a strain-sensitive element, typically a metal foil or wire, which is attached to the object being measured. As the object twists, the strain gauge experiences a change in resistance, which can be measured and converted into torque readings.

What are the applications of torsional strain gauges?

Torsional strain gauges have a wide range of applications in various industries, including automotive, aerospace, and manufacturing. They are commonly used for torque measurement in engines, turbines, and other rotating machinery, as well as in the testing and development of new products.

What factors should be considered when purchasing a torsional strain gauge?

When purchasing a torsional strain gauge, it is important to consider factors such as the required measurement range, accuracy, and compatibility with the object being measured. Other considerations may include environmental conditions, such as temperature and humidity, and the availability of necessary accessories and software for data collection and analysis.

How do I choose the right torsional strain gauge for my needs?

Choosing the right torsional strain gauge depends on the specific requirements of your application. It is important to carefully evaluate the technical specifications and capabilities of different gauges, as well as any potential limitations or trade-offs. It may also be helpful to consult with a specialist or manufacturer to ensure the best fit for your needs.
