热销美国UE真空开关J400系列全现货供应
美国UE真空开关为纯机械形变导致微动开关动作。当压力增加时,真空开关作用在不同的传感压力元器件(膜片、波纹管、活塞)产生形变,将向上移动,通过栏杆弹簧等机械结构,zui终启动zui上端的微动开关,使电信号输出。机械压力开关设定方式从功能原理上均为连续位移型,设定点可单点设定并zui多可达到3个不同的设定点。
美国UE真空开关是控制管路或某封闭空间的真空度的开关,为纯机械形变导致微动开关动作。
美国UE真空开关是框架式断路器的通俗称呼,实际上就是断路器,主要作用是切断大电流的电器元件。
美国UE真空开关有负压及正负压兼顾的不同量程段的多种选择。在测负压的同时,UE真空开关可以耐受一定强度的正压,在电力行业有极广泛的应用。
