Frequently Asked Questions

A strain gauge is a sensor that measures the deformation or strain of an object due to an applied force or stress. The gauge works by measuring the change in electrical resistance of a thin metallic wire or foil bonded to the surface of the object being measured.

There are several types of strain gauges, including foil strain gauges, semiconductor strain gauges, and thin-film strain gauges.

Strain gauges are commonly used in the field of mechanical engineering to measure the stress and strain on a wide range of materials and structures, including bridges, aircraft, pipelines, and machinery. They are also used in biomedical research, materials science, and other fields to measure the deformation of various objects and materials.

The accuracy of a strain gauge depends on several factors, including the quality of the gauge, the sensitivity of the instrument, and the level of environmental control during the measurement. Generally, strain gauges can provide accurate measurements within a few percentage points.

When choosing a strain gauge, it's important to consider the specific requirements of your measurement, including the expected range of strain, the type of material being measured, and the environmental conditions of the measurement. Other considerations may include the size and shape of the object, the level of accuracy required, and the type of instrumentation and software needed for data analysis.

Installing a strain gauge requires carefully bonding the gauge to the surface of the object being measured and connecting it to a sensitive instrument or data acquisition system. Proper installation techniques are critical for obtaining accurate and reliable measurements.
