| description | The utility model discloses a fixed type load sensor for pumping unit well testing indicator diagram used in the petroleum industry, which is used when pumping unit well tests indicator diagram. The device comprises a hollow elastic body. Ten strain gauges are pasted on the outer surface of the elastic body, in which four strain gauges are transverse strain gauges, four strain gauges are vertical strain gauges and two strain gauges are temperature compensation strain gauges. The transverse strain gauges and vertical strain gauges are distributed at intervals along the elastic body, the two temperature compensation strain gauges are pasted below two diagonal vertical strain gauges, and the pasting directions are in accord with the vertical strain gauges, and the center angle of each strain gauge is a arbitrary angle among 44-46 degrees. Compared with the existing sensors, the utility model increases the uniformity of strained induction, and reduces the measurement error caused by the eccentricity of field installation. |
