FW MURPHY液位开关LS200系列介绍
LS200系列液位开关专为恶劣的气体压缩机洗涤器应用而设计，采用坚固的设计，仅在液位上升时跳闸。提供电动和气动两种型号，仪器可以直接拧入容器中，也可以通过外部浮子室安装。镀镍主体提供增强的腐蚀保护，而304不锈钢浮子可在0.55比重和较重的流体中运行。
附加功能包括：
额定工作压力为 2000 psi (13.8 MPa) [138 bar]
不锈钢型号可用于腐蚀性环境
LS200NDVO 是不带压力调节器的自卸阀操作器 (DVO)，适用于系统提供过滤调节器以将仪表质量的空气或气体作为控制介质的应用。
Designed for harsh gas compressor scrubber applications, the LS200 Series Liquid Level Switches feature a robust design that trips on rising liquid level only. With both electric and pneumatic models available, the instruments screw directly into the vessel or can be mounted via an external float chamber. The nickel-plated body provides enhanced corrosion protection while the 304 stainless steel float operates in 0.55 specific gravity and heavier fluids.
Additional features include:
Rated for 2000 psi (13.8 MPa) [138 bar] working pressure
Stainless steel models available for corrosive atmospheres
LS200NDVO is the Dump Valve Operator (DVO) without the pressure regulator for those applications where the system provides a filter regulator for instrument-quality air or gas as the control medium.
