Design of unbalanced bridge for temperature measurement

Unbalanced bridges are used for temperature measurements with accuracy of 0.1 to 10% which is needed in industrial application. The principle of operation and the design aspects of the same are discussed in detail taking into consideration over all non-linearity and sensitivity of measurement, component tolerances and temperature coefficients, bridge supply etc. The actual circuit arrangement and span adjustments are also explained in brief.
