详细介绍:
西门子流量计的产品说明: 原理:所有的电磁流量计都是基于法拉第电磁感应定律设计: UM=B.V.D.K测量电压产生于各流体的流向正交的电磁场。由两个电极 获得测量电压 B=磁通过密度,穿过流体介质并正交于流体流向 V=介质流速 D=测量管道内径 K=比例系数或传感器常数 电磁流量计的功能各测量原理 电磁流量计通常由一个内表面不导电的测量管、串联连接且沿管道 径向安装的电磁线圈以及至少两个电极组成。电极插入管壁并与被 测介质相接触。电流通过的磁场线圈产生的一个脉冲电磁场,其磁 通密度B垂直于管道轴线 诊断: 明确的文字标识和故障记录座断功能是仪表的基本功能 故障分类:功能;报警;持久性和重大错误,变送器自检:线圈和 电极测试过载 空管:半满管;低导电率;电极污垢 校验-步骤 SITRANS F M MAGFLO流量计的校验过和包括下列几个测试步骤 变送器测试 流量计和电缆绝缘测试 传感器磁性测试。 西门子流量计7ME系列一级代理 联系人:朱溪。手机:13818647848 QQ:928114553 QQ: 1250103578 7ME6910-1AA30-0AA0 7ME6130-1MA20-2AA1 7ME6140-3FA21-1CA1 7ME6520-5YF12-2AA1 7ME6310-8YA11-1AA1
