Calculators VISHAY

Unique strain-gage-related mathematical equations are provided throughout Micro-Measurements technical literature. To assist customers with the use of these equations, Micro-Measurements offers a series of calculators that require only the input of the required variables to obtain an instant calculated result. A list of the available calculators appears shown below. Don'thesitate to contactus with any questions : Contact Us

Bridge Output (mV/V) :

One Active Gage (tension/compression)

   outilscalcul1
     

Two Active Gages. Two active gages in uniaxial stress field - one aligned with maximum principal strain, the other with transverse "Poisson" strain.

   outilscalcul2
     
Two Active Gages. Two active gages with equal and opposite strains, typical of bending-beam arrangement.   outilscalcul3
     

Two Active Gages. Two active gages with equal strains of the same sign, used on opposite sides of column with low thermal gradient (bending cancellation, for instance.)

   outilscalcul4
     

Four Active Gages. Four active gages in uniaxial stress field, two aligned with maximum principal strain, the other two with transverse "Poisson" strain (beam).

   outilscalcul6
     

Four Active Gages. Four active gages in uniaxial stress field, two aligned with maximum principal strain, the other two with transverse "Poisson" strain (column).

   outilscalcul5
     

Four Active Gages. Four active gages with pairs subjected to equal and opposite strains (beam in bending or shaft in torsion).
