BURKERT流量传送177460子设备模块可被作用流量传送器(仅带有“Low Power”式脉冲传感器,型号为 8020、8030 和 8070)或脉冲分配器(带有所有样式的传感器,型号 8020、8030 和 8070)。模块会处理传感器的输出信号,显示测得的流量并以 mA 为单位或以脉冲的形式将其发送到信号输出端上。作为流量传送器运行时,传感器的频率信号会被转换成一个 4 - 20 mA 信号(双线运行)。作为脉冲分配器运行时,输入频率会被转换成一个可调节的输出频率。通过操作单元,可在两种运行模式之间进行切换。
BURKERT流量传送器177460点:
受微型控制器控制的电子设备
双线 (4-20 mA)/三线 (NPN/PNP) - 运行
可插接到流量传感器 8020、8030 或 8070 上
可拆除的操作单元
