秦控UE差压开关J402K-S147B 双点差压开关
工作原理
差压开关由2个膜盒腔组成，两个腔体分别由两片密封膜片和一片感差压膜片密封。高压和低压分别进入差压开关的高压腔和低压腔，感受到的差压使感压膜片形变，通过栏杆弹簧等机械结构，***终启动***上端的微动开关，使电信号输出。
UE 400系列压力开关、差压开关和温度开关是一种多用途的UE压力开关，此压力开关适用于需要多点输出和控制的场合，还可用于报警、关断、预警、高低限和液位控制功能。全天候系列压力开关有多种微动开关和多种过程接口的选择，使得400系列UE压力开关可以满足各种不同的需求，它广泛应用于保护与控制、工业过程装置、泵、气轮机、压缩机、纸浆、造纸、水和污水处理等场合。
