UE 产品的优点：
◆ 产品种类齐全
1/ 压力开关可调范围从-0.1 到62MPA
2/ 温度开关从-50到538摄氏度
3/ 差压开关的可调范围从-0.1 到3.45MPA
3/ 传感元件有膜片，波纹管，活塞3种形式
4/ 有特殊场所使用的开关，也有专为OEM用户设计的小型价格低廉开关
5/ 既有固定死区也有可调死区压力开关
6/ 部分机械式差压和温度开关可带现场指示
7/ 有2英寸压力接口防堵式开关也有卫生型平面膜片式开关
◆ 产品结构紧凑，经久耐用，外形美观，加工精细
◆ 焊接不锈钢设计结构
许多型号的压力开关采用了焊接不锈钢膜片或焊接不锈钢波纹管结构，省略了“O”型环，这种无泄漏的设计提高了危险防爆区域的防火性能，同时提高了耐压性。
