ATE-E310A **压力变送器
**压力变送器的概述
ATE-E310A**压力变送器用于测量气体、液体和蒸汽的压力,然后转变成4~20mADC的电流信号输出。ATE-E310A可与HART?275手操器相互通讯,进行设定、监控等。**压力变送器的标准规格 (以标准零点为基准调校量程,接液部分材质代码“S”和硅油)**压力变送器的性能规格调量程的参考精度(包括从零点开始的线性、滞后性和重复性)±0.15%或±0.20%(L膜盒)±0.075%(高精度型)若量程小于X±[0.1+0.05X]%或量程±[0.15+0.5X]%(L膜盒)量程2±[0.025+0.05X]%(高精度型)量程X取值:膜盒XkPa{psi}--------------------L5.4{22inH2O}M21.8{3.2}A250{36}
