Prosonic S FDU91
产品描述
非接触式连续测量物位和流量的超声波探头

与FMU90/FMU95变送器配套使用

优点

  • 非接触式测量方法; 降低了维护需要

  • 集成温度探头用于校正超声波运行时间。即便处于温度变化的环境之中,也可得到准确的测量结果.

  • PVDF密封焊接的探头,具有极高的抗化学腐蚀能力

  • FMU90 /FMU95变送器能自动识别探头类型,因此调试十分简单

  • 探头和变送器能分离安装,最长间距达300m

  • 探头可与变送器分离进行安装,能适应恶劣的外部工作环境

  • 探头的自清洗功能有效地降低了粘附现象发生的可能性

  • 探头配备的一体化加热器用于防止探头表面结冰(可选),以确保可靠测量

  • 抗侵蚀,防水型 (IP68)

  • 通过粉尘防爆(Dust-Ex)认证和气体防爆(Gas-Ex)认证(ATEX, FM, CSA, TIIS)

应用领域

  • 对液体,糊状物,浆料,粉料及表面粗糙的固体块状物进行连续的非接触式物位测量

  • 对明渠和测量堰进行流量测量

  • 最大测量范围:
    液体: 10m
    块料: 5m

  • 适用于爆炸危险区域
