"Mechanical Strain gauges" do not have inductance.
There are many types of strain gauge: Mechanical, photoelastic, electrical etc....
Are you wanting the inductance of an electrical strain gauge? if so which type?
the types are1> mechanical strain gauge like single bonded rosette2> electrical resistance strain gauges3> elliptical c/s gauge. e..g bourdon tube etc.
* a device that responds to mechanical strain. with a small change in resistance. ... * device for determining the amount of strain (change in dimensions) when a stress is applied
A strain gauge is a device used to measure mechanical strain, which is the deformation of an object under stress. It works by changing its electrical resistance in response to the strain applied to the object it is attached to. This change in resistance is then converted into a measurable electrical signal that can be used to determine the amount of strain the object is experiencing.
Factors affecting the accuracy of strain gauges include temperature fluctuations, mechanical stress on the gauge, incorrect mounting techniques, and electrical noise interference. These factors can lead to variations in the resistance of the strain gauge, impacting the accuracy of the strain measurement.
these are very costly and cannot meet all the requirements. the values we get from this are also not exact .so,electrical strain come into progress
How I know if the strain gauge is gone
Pressure Indicator is any instrument that indicates pressure. Pressure Gauge is also a type of pressure Indicator. It is a mechanical device. Pressure indicators can work on mechanical deflection (in case of pressure gauge) or Piezo electric effect, change in capacitance, change in inductance etc. These are generally digital type instruments.
Advantages and disadvantages of strain gauge
it is more sensitive small gauge size low hysteresis
You can increase the sensitivity of a force sensor using a strain gauge by either increasing the gauge factor (by using materials with higher sensitivity to strain) or by increasing the strain applied to the gauge (by increasing the length or width of the gauge). Both methods will increase the change in resistance of the strain gauge in response to applied force, resulting in higher sensitivity.
Load cells are strain gauge based sensors used for weighing applications.
A strain gauge extensometer is a device used to measure the deformation (strain) of an object under stress. It consists of a strain gauge, which is a sensor that detects changes in resistance due to deformation, and a mechanical structure that ensures accurate placement on the test specimen. Extensometers are commonly used in materials testing to monitor how materials respond to applied forces, providing critical data for engineering and research applications. Their precise measurements help in assessing material properties and structural integrity.
