Abstract
A temperature compensated strain gauge amplifier derives compensating signals for offset and gauge errors of bridge transducers from a single temperature sensing element. The amplifier is inexpensive to construct, provides a high degree of voltage linearity with respect to temperature and is reliable in operation.
