Strain Gauge

Strain gauges form the fundamental measurement base for most of the experimental and on-site test setups. As well as direct strain measurements in full/half and quarter bridge configurations, many transducers used in Civil, Mechanical, Mining, Metallurgy, Materials & Geology Engineering are manufactured by bonding strain gauges on a metal setup. Load cells & many displacement/deformation gauges are manufactured in this way.

Strain gauges are used for stress/strain or load/deformation measurements in Structural Health Monitoring. Besides they are one of the indispensable components of academic research studies and laboratories. 

Uniaxial/ Biaxial/ Rosette Ty[e Strain Gauges

Wheatsone bridge is essential for direct strain gauge measurements. A wheatstone bridge involves 4 resistors, which among those at least one resistor is the strain gauge itself. 

An excitation voltage is applied to one section of the Wheatstone bridge, and resistance change due to the deformation of gauge (where it is bonded) is acquired from the other section. 

4 strain-gauges are needed for full-bridge configurations. On the other hand, different options of quarter-bridge & half-bridge configurations are also used for measuring axial or bending strains in different architectures depending on the material, geometry and the aim of the application.
