- 适用的最高过程温度可达200 °C (392 °F).
- 支持HART 或PROFIBUS PA以及FF基金会现场总线协议.
- 可选远程显示和操作单元
-
用于物位监测(MIN, MAX) ,符合 IEC 61508/IEC 61511-1标准的要求,通过了SIL 2 认证
应用领域
Micropilot M可用于对粉末及颗粒状固体物料进行连续的非接触式物位测量,也可对液体进行物位测量。
测量不受粉尘,进料噪声,温度分层和气体分层的影响。
典型的应用领域:
- 粉尘严重的高固料仓(如水泥生料或动物饲料)中的物位测量
- 可用于温度高达200 °C (392 °F)的测量场合, 如熟料或飞灰。
- 可对具有强研磨作用的固料进行物位测量,如铁酸盐
喇叭尺寸为DN80或DN100的FMR250,适用于所有的标准应用场合,尤其适用于小尺寸安装短管的测量场合。
喇叭尺寸为DN200 或 DN250的FMR250,采用抛物面喇叭,波束角只有4° 或 3.5°,可用于多种测量场合
