S287 电容式液位开关 - 飞线型液位开关
冷却液位开关，提供水槽和/或源输出。配有飞线，客户可选择合适的3或4针连接器。
S285是一个主动式装置，设计用于在液体低于或高于预设的液位时发出报警信号。它可以指定一个延迟，以消除由于湍流引起的误报。
该开关包含一个工厂可编程的微处理器，可提供沉降至地或源电压输出。它的占地面积小，对水箱的侵入有限，意味着降低了损坏的风险，而且有多种客户指定的选项，使其适用于大多数应用。
该开关可在接地的金属罐和隔离的塑料罐中工作。为了实现高精度，S285最好是水平安装在需要报警或控制信号的地方。但是，该开关也可以垂直安装，请联系Fozmula公司，了解您的应用需求。
