Strain Gauge Pressure Sensor Principle : When a closed container is subjected to the appilied pressure, it is strained (that is, its dimension changes). Measurement of this strain with a secondary transducer like a strain gauge ( metallic conductor) becomes a measure of the appilied pressure. That is, if strain gauges are attached to the container subjected to the applied pressure, the strain ...

· A strain gauge is a sensor whose measured electrical resistance varies with changes in strain. Strain is the deformation or displacement of material that results from an applied stress. Stress is the force applied to a material, divided by the material’s cross-sectional area. Load cells are designed to focus stress through beam elements where strain gauges are located. Strain gauges convert ...
· A strain gauge is a type of electrical sensor. It’s primary use is to measure force or strain.

A Strain gauge (sometimes refered to as a Strain gage) is a sensor whose resistance varies with applied force; It converts force, pressure, tension, weight, etc., into a change in electrical resistance which can then be measured. When external forces are applied to a stationary object, stress and strain are the result. Stress is defined as the object's internal resisting forces, and strain is ...
