新型电阻应变式土压力盒传感器
摘要：
一种新型电阻应变式土压力盒传感器，包括土压力盒侧壁、土压力盒端盖，所述土压力盒侧壁固定在土压力端盖上，所述土压力盒侧壁一端设有受力膜，所述受力膜底面设置环形电阻应变片，所述传感器还包括外罩和橡胶传力块，所述土压力盒侧壁上套装所述外罩，所述外罩底面与受力膜之间设置所述橡胶传力块。本发明提供一种灵敏度较高、标定简易的新型电阻应变式土压力盒传感器。
摘要（英）：

A novel resistance strain type earth pressure cell sensor comprises an earth pressure cell side wall and an earth pressure cell end cover, wherein the earth pressure cell side wall is fixed to the earth pressure cell end cover, a stress film is arranged at one end of the earth pressure cell side wall, and an annular resistor strain gauge is arranged on the bottom surface of the stress film. The sensor further comprises an outer cover and a rubber force transmission block, wherein the earth pressure cell side wall is sleeved with the outer cover, and the rubber force transmission block is arranged between the bottom surface of the outer cover and the stress film. The novel resistance strain type earth pressure cell sensor is high in sensitivity and easy to calibrate.
