美国UE进口压力开关H400-S126B 压力开关UE
原理
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，终启动上端的微动开关，使电信号输出。机械真空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多可达到3个不同的设定点。UE真空开关有绝对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，真空开关可以耐受一定强度的正压。
UE真空开关广泛的应用：
● 真空泵行业的压力控制
● 凝汽器的真空环境的保持监控。
● 工业过程报警器和快速关断应用
● OEM 机器设备的极限保护应用
● 水处理系统
● 泵和压缩机
● 滤网工作状态监测
● 流体的保护
● 热水加热器和锅炉
● HVAC 设备
● 高纯度去离子水系统、除湿设备和清洗设备
