Показать описание
By using an instrument called Wheatstone's resistance measuring bridge, unknown resistance values can be determined very precisely. This can then be used to infer, for example, temperature, light intensity, or mechanical deformation due to a specific mass. From the content:

Given a pressure of 2kpa, nominal resistance of 120 ohm, diameter of strain gauge 0.1mm, a GF of 2. What will be the change in resistance value of the strain gauge?

ram.

can the 4 gauges of a complete bridge be placed on the same face? None in compression
