主要特点 Main features

轨压传感器用于精确测量共轨管内压力，压力通过盲孔传到膜片上，膜片产生形变，使膜片上的硅片电阻值变化并引起电桥电压值变化，再通过芯片调整放大，产生线性电压，反馈到ECU，再通过ECU内存储的特性曲线计算出压力值。

Rail pressure sensor measures the fuel pressure in the common rail.As soon as the pressure travels through a blind hole to the membrane,it bends the membrane with a change of silicon slice resistance value and bridge voltage.The change is then amplified into linear voltage and reflected back to ECU.The final pressure value is calculated with a specially stored characteristic curve.
