What Is a Strain Gauge?
A strain gauge is a measuring instrument to measure the strain of an object. Strain is the amount of deformation of a material when an external force is applied to it. Strain is measured to determine the stress and evaluate the strength and reliability of a structure.
A strain gauge sensor detects the strain in a material, and this minute voltage signal is input to a Strain gauge to measure the amount of strain. Strain gauges are capable of such multi-channel measurement.
Uses of Strain Gauges
Strain gauges are indispensable measuring instruments to ensure the strength and reliability of structures. In addition to stress, Strain gauges can also measure physical quantities such as temperature, pressure, load, and displacement.
Because of this versatility, Strain gauges are used in various industries, including automotive, industrial machinery, electronics, and metal and steel. Hydraulic excavators, for example, are used under severe conditions such as excavating soil and breaking bedrock. Therefore, Strain gauges are used in research and development to evaluate the strength of structures.
Principle of Strain Gauges
There are various strain gauges, but here we introduce the principle of strain gauges that connect strain gauges via a bridge box.
First, strain gauges are used to detect the strain of an object. Strain gages have the principle of changing electrical resistance as the structure expands and contracts. This change in electrical resistance is measured to detect strain. Next, in a bridge box, the electrical resistance seen by the strain gauge is converted into a change in voltage using a bridge circuit. This signal is then taken into the strain gauge. Since the voltage obtained from the bridge box is minute, the signal is amplified by a built-in amplifier. The amplified signal is converted to AD, and the signal is output to a PC. Some Strain gauges have a built-in bridge box.
Strain gauges can measure static strain (static strain) to dynamic strain (dynamic strain) of several hundred kHz caused by shocks, etc.
