【H400K-457 20-210KPa】进口UE差压控制器单点输出,内部调整,有参考刻度
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。
优点:
1. 动作点稳定,不会受冲击、振动温度变化或其它环境条件影响。
2. 不会因压力的波动而引起接点抖动,清晰明朗的开或关状态。
3. 不受泵的冲击、接点的振动疲劳等的影响。
3. 不受泵的冲击、接点的振动疲劳等的影响。
4. 寿命长,稳定性及动作重复性高。
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。
