产品特色

• 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。

• ?

• 型号- 901.21?
