Strain Gauge Pressure Sensor Principle - Inst Tools

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 ...

What is a Strain Gauge? - Sensors and Transducers

07/11/2019· A strain gauge is a type of electrical sensor. It’s primary use is to measure force or strain. The resistance of a strain gauge changes when force is applied and this change will give a different electrical output. Strain gauges use this method to measure pressure, force, weight and tension. When external forces are applied to a stationary ...

A strain gauge is a sensor, which results in change of resistance due to the applied force. The parameters like force, pressure, etc. are converted into measureable electrical resistance. To a stationary object, when external forces are applied, it results in stress and strain. So here, stress is defined as internal resistance of the object and strain is given as displacement and deformation. If L
