<p>5695-413 E. Romo 2 BRIDGE CIRCUIT A circuit including a strain gage bridge to produce an electrical signal from a mechanical deflection. The circuit has a differential amplifier to supply a constant current to the bridge. Linearization and accuracy are obtained through a feedback connection to the differential amplifier. The constant current feature, a temperature compensation feature and a common mode rejection feature are employed to improve accuracy. A constant current source for a bridge is new in the art.</p> |
