　　差压变送器是一种典型的自平衡检测仪表，它利用负反馈的工作原理克服元件材料、加工工艺等不利因素的影响。差压变送器用于防止管道中的介质直接进入变送器里，感压膜片与变送器之间靠注满流体的毛细管连接起来。它用于测量液体、气体或蒸汽的液位、流量和压力，然后将其转变成4～20mA DC信号输出。差压变送器所测量的结果是压强差，即△P=ρg△h。而由于油罐往往是圆柱形，其截面圆的面积S是不变的，那么，重力G=△P·S=ρg△h·S，S不变，G与△P成正比关系。即只要准确地检测出△P值，与液位高度h成反比，与高度差△h成正比，在温度变化时，虽然油品体积膨胀或缩小，实际液位升高或降低，所检测到的压力始终是保持不变的。如果用户需要显示实际液位，也可以引入介质温度补偿予以解决。
