Static resistance strain gauge

Provided is a static resistance strain gauge. Relates to a resistance strain gauge, in particular to improvement of a static resistance strain gauge. Comprising a first power supply loop and a second power supply loop which are used for providing power, the first power supply loop supplies power to the filtering and acquisition module, and the second power supply loop supplies excitation voltage to the bridge circuit module; a dual-power mode is adopted, and a voltage sampling method is adopted for measuring point bridge circuit excitation voltage, so that when the measuring points of the strain gauge change, the measuring point bridge circuit excitation voltage is constantly equal to 2V, the initial value of each measuring point is not affected, and the strain measurement precision is improved. 静态电阻应变仪。涉及一种电阻应变仪，尤其涉及静态电阻应变仪的改进。包括用于提供电源的第一供电回路和第二供电回路，所述第一供电回路给所述滤波和采集模块供电，所述第二供电回路给桥路模块提供激励电压；采用了双电源模式，测点桥路激励电压采用电压采样方法，使得应变仪测点变化时，测点桥路激励电压恒等于2V，并且每个测点初始值不受影响，提高了应变测量精度。
