德国Beck品牌 901.21111M4真空压力开关 真空集便器定制压力开关
产品介绍
产品描述
生产厂家：德国Beck公司
产品名称：真空压力开关
产品型号：901.21111M4
采购号：16645-0061
产品类型：机械式压力开关
产品效果图
黄铜连接材料的BECK真空压力开关，
塑料连接材料的beck压力开关
产品特色
经典应用-动车真空系统真空度监测
正常状态下，动车组真空集便器的真空系统的真空发生器会持续抽真空，车上的真空收集系统工作是会破掉真空，这样
真空系统内的真空会保持在一定值内。
但是在真空收集系统发生故障的时候，产生的真空会越来越大，以致会危害系统的安全，此时 beck的901真空压力开关
就起到了警报作用，当真空度上升到真空开关设定值的时候，901.21真空开关会发出报警信号，真空发生器停止工作；单真空度
下降到一定值的时候，901.21负压开关报警信号消失，真空发生器正常工作。
推荐型号- 901.21
