Strain gauges are an essential tool when it comes to measuring stress and strain for various applications, from industrial machinery to biomedical research. To get accurate results, you need to know how to use a strain gauge correctly and calculate its readings. This is where a strain gauge calculator comes in handy.
A strain gauge calculator is a simple tool that helps you calculate the electrical resistance of a strain gauge based on the measured strain. In this article, we'll walk you through everything you need to know about using a strain gauge calculator, so you can get the most accurate results possible.
What is a Strain Gauge?
Before we dive into strain gauge calculators, let's first understand what a strain gauge is and how it works.
A strain gauge is a sensor that measures microscopic changes in electrical resistance as an object undergoes stress or strain. These changes are proportional to the amount of deformation in the object and provide valuable insight into the object's mechanical behavior.
Strain gauges consist of a thin strip of metal (usually aluminum or nickel) that is bonded to the surface of the object being measured. When the object undergoes deformation, the metal strip also stretches or contracts, changing its length and thickness and thereby altering its electrical resistance.
How to Use a Strain Gauge Calculator?
Using a strain gauge calculator is a straightforward process. The inputs required for the calculator are as follows:
- The gauge factor of the strain gauge
- The electrical resistance of the strain gauge
- The measured strain
- The nominal resistance of the strain gauge
The gauge factor of a strain gauge is a dimensionless constant that represents the ratio of the fractional change in electrical resistance to the fractional change in length. Most strain gauges have a gauge factor between 2 and 6.
The electrical resistance of a strain gauge is the resistance measured between its two terminals when there is no strain or stress applied to it. This value is usually specified by the manufacturer.
The measured strain is the deformation in the object being measured, expressed as a decimal or percentage. This value can be obtained using various sensors, such as force sensors or displacement sensors.
The nominal resistance of a strain gauge is the resistance specified by the manufacturer as the design resistance of the gauge, usually 120 Ω or 350 Ω.
Once you have these inputs, you can use a strain gauge calculator to determine the actual electrical resistance of the strain gauge based on the measured strain.
