德国E+H固体雷达物位计FMR250-AEE1XCJAA2K适合测量高位贮仓中粉尘严重的固体散料，也适合高研磨作用的固体散料

应用领域

FMR250用于测量高位贮仓中粉尘严重的固体散料，例如水泥、生料或动物饲料等；可应用于温度达200 °C (392 °F)的场合如水泥孰料或飞灰；可应用于具强研磨作用的固料如铁素体。配备DN80或DN100喇叭型天线的FMR250用于标准型应用和小型尺寸的安装短管。FMR250因配备的DN200或DN250抛物形天线的波束角只有4°或3.5°，成为适用许多安装场合的理想仪表

FMR250-AEE1XCJAA2KMicropilot FMR250特别适合测量高位贮仓中的固体散料、也适合高温场合和高研磨作用的固体散料。FMR250内置空气清洁器，适用粉尘严重或介质黏附的工况条件。Micropilot FMR250适合粉状、粒状等固体散料的连续性、非接触式物位测量。测量值不受粉尘、进料噪音、温度层、气体层的影响。

优势

• 非接触式测量：测量几乎不受介质特性影响

• 两线制技术，价格低廉：真正代替了压差、浮子或浮筒式物位测量方法

  两线制技术节约布线成本，方便接入现有系统

• 利用Endress+Hauser操作软件，方便仪表调试、文件建档和故障诊断

• 通过菜单式的字母数字显示模块，现场操作简便

• 可进行限位监控（高限，底限），通过 IEC 61508 和 IEC 61511认证，达到SIL2功能安全等级

• 支持HART或PROFIBUS PA等FOUNDATION基础现场总线协议

• zui远测量距离：70m(230ft)FMR250-AEE1XCJAA2K
