Static resistance strain gauge with bridge circuit capable of being connected in mixed mode

Provided is a static resistance strain gauge with a bridge circuit capable of being connected in a mixed mode. Relates to a static resistance strain gauge, in particular to a static resistance strain gauge with a bridge circuit capable of being connected in a mixed mode. Comprising a 1/4 bridge, a half bridge and a full bridge, the 1/4 bridge, the half bridge and the full bridge are respectively in signal connection with a multi-channel analog switch N1, a multi-channel analog switch N2 and a multi-channel analog switch N3, and the multi-channel analog switch N1, the multi-channel analog switch N2 and the multi-channel analog switch N3 control switching of the 1/4 bridge, the half bridge and the full bridge. The multi-path analog switch is adopted to replace a short-circuit sheet, and the control signal of the multi-path analog switch for switching the bridge circuit mode changes along with the change of a measuring point, so that the switching of the bridge circuit mode is realized, namely, the measurement o
