描述
在使用过程中应注意的事项。变送器在工艺管道上正确的安装位置与被测介质有关,为获效得最佳的测量果,应注意注意几点情况。第一点是防止变送器与腐蚀性或过热的介质接触;第二点是测量液体压力时,取压口应开在流程管道侧面,以避免沉淀积渣;第三点是防止渣滓在导管内沉积;第四点是测量气体压力时,取压口应开在流程管道顶端,并且变送器也应安装在流程管道上部,以便积累的液体容易注入流程管道中;第五点是测量蒸汽或其它高温介质时,需接加缓冲管(盘管)等冷凝器,不应使变送器的工作温度超过极限;第六点是导压管应安装在温度波动小的地方;第七点是冬季发生冰冻时,按装在室外的变送器必需采取防冻措施,避免引压口内的液体因结冰体积膨胀,导至传感器损坏;第八点是接线时,将电缆穿过防水接头或绕性管并拧紧密封螺帽,以防雨水等通过电缆渗漏进变送器壳体内;第九点是测量液体压力时,变送器的安装位置应避免液体的冲击,以免传感器过压损坏。
