一、产品概述：
罗斯蒙特的3051C压力变送器为压力测量技术创建了一个新的标准。罗斯蒙特3051压力变送器具有无可比拟的操作性能、灵活的CoPlanarTM平台，而且可以升级。新型罗斯蒙特3051C压力变送器的性能指标保证了在不同工况下的精度和稳定性。
工作原理：工作时，高、低压侧的隔离膜片和灌充液将过程压力传递给灌充液，接着灌充液将压力传递到传感器中心的传感膜片上。传感膜片是一个张紧的弹性元件，其位移随所受压而变化（对于GP表压变送器，大气压如同施加在传感膜片的低压侧一样）。AP绝压变送器，低压侧始终保持一个参考压力。传感膜片的最大位移量为0.004英寸（0.1毫米），且位移量与压力成正比。两侧的电容极板检测传感膜片的位置。传感膜片和电容极板之间电容的差值被转换为相应的电流，电压或数字HART（高速可寻址远程发送器数据公路）输出信号。
罗斯蒙特3051压力变送器的应用
新型罗斯蒙特3051C的性能指标保证在不同工况下的精度和稳定性。灵活可变的CoPlanarTM平台设计不但为您目前的应用需求提供最佳方案，同时通过PlantWeb工厂管控网和现场总线技术也完全能满足您将来的技术要求。
