美国omega LVK-22液位开关
液位开关 LVK10,LVK20,LVK30 Series 液位开关 成本低，通用级监控 紧凑的设计 坚固耐用，耐冲击和振动 安装垂直在罐的顶部或底部 对于高重复性磁簧开关的设计 User Selectable, Normally Open or Normally Closed SPST Switch The LVK-10 Series level switches feature a small float displacement, especially suited for narrow or restricted areas. A standard 1 /8 " NPT male fitting for LVK-10 and LVK-20 series allows for quick installation in either the top or bottom of the tank or vessel. LVK-30 has a 1/4" NPT. A sealed SPST switch provides consistent accuracy and high repeatability with the effects of shock, vacuum or vibration minimized. Extremely versatile, the switch is user selectable as normally open or normally closed by simply removing the retaining clip and inverting the position of the float. For intermediate float displacement, the LVK-20 Series will yield long life and greater stability for a broad range of level monitoring requirements. The LVK-30 Series larger float displacement is intended for use with liquids of high viscosity, and is well suited for harsh environments. Both models share the standard features of the LVK-10. The float is made from Buna-N and the stem is either stainless steel or brass.
