2051CD2A22A1AB4M5I1罗斯蒙特2051TG压力变送器

一、产品概述：
　　罗斯蒙特的2051TG压力变送器，Rosemount2051TA绝压变送器集传感器、电子技术与单隔离膜片设计与一体，实现表压和绝压测量的校验量程从0.3到10000psi。罗斯蒙特2051TG压力变送器工作原理：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。罗斯蒙特2051压力变送器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2051GP压力变送器，大气压如同施加在传感膜片的低压侧一样）。罗斯蒙特2051AP绝压变送器，低压侧始终保持一个参考压力。传感膜片的较大位移量为0.004英寸（0.1毫米），且位移量与压力成正比。两侧的电容较板检测传感膜片的位置。传感膜片和电容较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。
