罗斯蒙特3051TA2A2B21A 一、工作原理 罗斯蒙特的3051T型压力变送器集传感器、电子技术与单隔离膜片设计于一体,实现表压和绝压测量的校验量程从0.3到10000psi 。3051T型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。3051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3051GP压力变送器,大气压如同施加在传感膜片的低压侧一样)。3051AP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。 二、技术参数 性能优异:精度0.04% 绝压:校验量程从0.3至10000psi 表压:校验量程从0.3至10000psi 不锈钢与哈氏合金C?过程隔离膜片 灌充液:硅油与惰性油 可选DIN和与压力反应罐相配的过程相连 复合量程(**TG),可测量负压 三、罗斯蒙特的3051T型压力变送器选型 型号 变送器类型 3051TG 表压变送器 3051TA **压力变送器 压力范围 代码 3051TG 3051TA 1 0-0.3至0-30psig(0-2至0-207kPa) 0-0.3至0-30psig(0-2至0-207kPa) 2 0-1.5至0-150psig(0-10至0-1034kPa) 0-1.5至0-150psig(0-10至0-1034kPa) 3 0-8至0-800psig(0-55至0-5516kPa) 0-8至0-800psig(0-55至0-5516kPa) 4 0-40至0-4000psig(0-276至0-27579kPa) 0-40至0-4000psig(0-276至0-27579kPa) 5 0-2000至0-10000psig(0-13800至0-68900kPa) 0-2000至0-10000psig(0-13800至0-68900kPa) 代码 输出 A 4-20mA,带有基于HART协议的数字信号 M(1) 低功耗,1-5Vdc,带有基于HART协议的数字信号(0.8-3.2Vdc输出,用选项代码C2) 代码 过程连接型式 2A 1/4-18NPT阴螺纹 2B 1/2-14NPT阴螺纹 2C G1/2AA DIN 16288阳螺纹(仅**程1-4,SST) 2F 锥形和螺纹式,适用于F-250-C型蒸压器Autoclave(包括压盖与筛,仅**程5SST) 隔离膜片 过程连接液件材料 代码 2(2) 316L SST 哈氏合金C-276 3(3) 316L SST 哈氏合金C-276 代码 灌充液 1 硅油 2 惰性液(Fluorinert FC-43) 代码 外壳材料 导线管入口尺寸 A 铝,聚氨酯涂层 1/2-14NPT B 铝,聚氨酯涂层 M20×1.5(CM20) C 铝,聚氨酯涂层 PG13.5 D 铝,聚氨酯涂层 G1/2 J SST 1/2-14NPT K SST M20×1.5(CM20) L SST PG13.5 Rosemount罗斯蒙特3051CD差压变送器 3051CD0A02A1AB1H2L4M5 3051CD1A02A1AB1H2L4M5 3051CD2A02A1AB1H2L4M5 3051CD3A02A1AB1H2L4M5 3051CD4A02A1AB1H2L4M5 3051CD5A02A1AB1H2L4M5 3051CD0A02A1AB3H2L4M5 3051CD1A02A1AB3H2L4M5 3051CD2A02A1AB3H2L4M5 3051CD3A02A1AB3H2L4M5 3051CD4A02A1AB3H2L4M5 3051CD5A02A1AB3H2L4M5 3051CD0A02A1AB1H2L4M5K5 3051CD1A02A1AB1H2L4M5K5 3051CD2A02A1AB1H2L4M5K5 3051CD3A02A1AB1H2L4M5K5 3051CD4A02A1AB1H2L4M5K5 3051CD5A02A1AB1H2L4M5K5 3051CD0A02A1AB1H2L4M5E5 3051CD1A02A1AB1H2L4M5E5 3051CD2A02A1AB1H2L4M5E5 3051CD3A02A1AB1H2L4M5E5 3051CD4A02A1AB1H2L4M5E5 3051CD5A02A1AB1H2L4M5E5 3051CD0A02A1AB1H2L4M5I5 3051CD1A02A1AB1H2L4M5I5 3051CD2A02A1AB1H2L4M5I5 3051CD3A02A1AB1H2L4M5I5 3051CD4A02A1AB1H2L4M5I5 3051CD5A02A1AB1H2L4M5I5 3051CD0A02A1AB3H2L4M5K5 3051CD1A02A1AB3H2L4M5K5 3051CD2A02A1AB3H2L4M5K5 3051CD3A02A1AB3H2L4M5K5 3051CD4A02A1AB3H2L4M5K5 3051CD5A02A1AB3H2L4M5K5 3051CD0A02A1AB3H2L4M5E5 3051CD1A02A1AB3H2L4M5E5 3051CD2A02A1AB3H2L4M5E5 3051CD3A02A1AB3H2L4M5E5 3051CD4A02A1AB3H2L4M5E5 3051CD5A02A1AB3H2L4M5E5 3051CD0A02A1AB3H2L4M5I5 3051CD1A02A1AB3H2L4M5I5 3051CD2A02A1AB3H2L4M5I5 3051CD3A02A1AB3H2L4M5I5 3051CD4A02A1AB3H2L4M5I5 3051CD5A02A1AB3H2L4M5I5 3051CD1A22A1AB4M5 3051CD2A22A1AB4M5 3051CD3A22A1AB4M5 3051CD4A22A1AB4M5 3051CD5A22A1AB4M5 3051CD1A22A1AB4M5DF 3051CD2A22A1AB4M5DF 3051CD3A22A1AB4M5DF 3051CD4A22A1AB4M5DF 3051CD5A22A1AB4M5DF 3051CD1A22A1AB4M5K5 3051CD2A22A1AB4M5K5 3051CD3A22A1AB4M5K5 3051CD4A22A1AB4M5K5 3051CD5A22A1AB4M5K5 3051CD1A22A1AB4M5E5 3051CD2A22A1AB4M5E5 3051CD3A22A1AB4M5E5 3051CD4A22A1AB4M5E5 3051CD5A22A1AB4M5E5 3051CD1A22A1AB4M5I5 3051CD2A22A1AB4M5I5 3051CD3A22A1AB4M5I5 3051CD4A22A1AB4M5I5 3051CD5A22A1AB4M5I5
