涡轮流量计TM值

对于磨粒 对于攻击媒体 排队

功能涡轮转子安装在两个转子轴上的不锈钢壳体中。轴承的材料是PTFE或碳化钨。这意味着可以测量甚至侵蚀性或略微磨料的流体。介质通过涡轮叶片，使转子轮以与流体速度成比例的速度旋转。当每个转子叶片穿过由换能器产生的磁场时，产生电压输出。前置放大器将窦波转换为方波信号。防爆设计（ATEX）•所有涡轮机流量计可根据ATEX进行防爆设计。•防爆设计包括涡轮机流量计（本质安全电气设备）和开关放大器K 130（相关电气设备）。保护类型“内在安全”适用于这种结构。•涡轮机流量计安装在潜在的爆炸性气氛中。 • The mounting of the amplifier K 130 is carried out in the safe area. • Turbine flow meter and switching amplifier are electrically connected to each other. The switching amplifier evaluates the sensor signals and converts them to square-wave signals. • Without switching amplifier, the turbine flow meter must not be operated in the potentially explosive atmosphere. • Cable lengths of up to 400 m are possible between turbine flow meter and switching amplifier. • LED’s for monitoring line breaks / short circuits, channel switching state and power supply are located on the switching amplifier.
