Murph液位开关L150, EL150K1, EL150EX发动机液位计
Murphy Level Switches: Engine Liquid, Bilge & Tank Level

L150, EL150K1, EL150EX – The liquid level Swichgage

 

L150 和 EL150K1 系列发动机液位计
L150 and EL150 Series Level Swichgage

L150系列液位开关是液位计和低位开关的组合,其
包括:(1)带浮球的腔室
(2)带指针的指示盘
(3)低位触点。
当正确安装和维护时,浮子带动指针,该指针在正常操作期间指示液位。如果液位下降到设定下限点时关闭开关电路。

产品应用:

L150/EL150K1主要用于发动机冷却系统,调压井或膨胀水箱,冷凝器散热器或汽相系统,加压或大气系统。还可用于监测润滑油,液压油或柴油储油罐,并在预设的低油位时激活警报和/或关闭设备。 L150/EL150K1用于低压系统,其最大L150 、EL150K1 及EL150EX 液位开关把液位显示仪表和低位开关结合在了一起。每个产品包含了: 浮子、指针、表盘及低液位触点。产品正常使用时, 浮子带动指针, 显示液位的同时, 在液位降至低位设置点时, 闭合开关电路。The L150 Series Level Swichgage instrument is a combination liquid level gauge and low limit switch; each unit includes a chamber with pivotal float, an indicating dial with pointer and a low level contact.


产品应用本液位开关系列产品主要应用在常压或加压的发动机冷却系统, 调压室或蒸发器, 冷凝器/ 冷却箱或水汽系统等。该产品也可被用于监控润滑油、液压油位或柴油机燃油罐和其他需要低位报警或停机的系统。When properly installed and maintained, the float operates the pointer which, in turn, both indicates level during normal operation, and closes a switching circuit if the level falls to the low-limit set point.

Manuals

The primary use of the L150/EL150K1 is for engine cooling systems, surge or expansion tanks, condenser radiator or vapor phase systems, pressurized or atmospheric systems. The Level Swichgage instrument can also be used to monitor lube oil, hydraulic fluid or diesel fuel reservoirs and activates alarms and/or shut down at a predetermined minimum level. These instruments are built for low pressure systems with a maximum of 25 psi (172 kPa) [1.72 bar].
