波登管的端部位移可用位移测量器直接显示出来,例如端部带动电位计的指示器、差动变压器的活动铁芯等均可直接显示位移。人们通过选择材料能够改进波登管传感器和调节器的性能,但对于波登管的尺寸设计,从前只能凭经验做近似给定。本文介绍的波登管工程计算方法,可设计计算波登管几何尺寸。椭圆截面或扁平圆截面的波登管承受压力 p 时发生变形,使管子横截面的长短半径之比 a/b 减小,波登管曲率半径增大,于是管的自由端产生位移。
The displacement of the Bourdon tube can be directly displayed by the displacement gauge. For example, the indicator of the end potentiometer and the movable iron core of the differential transformer can directly display the displacement. People choose materials to improve the performance of the Bourdon tube sensors and regulators, but the dimensions of the Bourdon tube have traditionally been approximated empirically. This article describes the Bourdon tube engineering calculation method can be calculated and calculated Bourdon tube geometry. Bourdon tubes with elliptical or flattened circular cross sections deform under pressure p, reducing the ratio of the length to the radius of the tube cross section, a / b, and increasing the radius of curvature of the bourdon tube, thus displacing the free end of the tube.
