Murphy EL150K1液位开关 15700116
EL150K1 Liquid Level Swichgage 15700116

EL150K1液位监测仪是液位计和低限位开关的组合;该仪器包括：

（1）一个带枢轴浮子的腔室，
（2）一个带指针的指示刻度盘，
（3）一个低电平触点。

正确安装和维护后，浮子操作指针，而指针又在正常运行期间指示电平，并在电平降至下限设定点时关闭开关电路。EL150K1的主要用途是发动机冷却系统、喘振或膨胀水箱、冷凝器散热器或气相系统、加压或大气系统。EL150K1液位监测仪还可用于监测润滑油、液压油或柴油油箱，并在预定的最低液位启动警报和/或关闭。

该仪器专为最大压力为 25 psi （172 kPa） [1.72 bar] 的低压系统而设计。

EL150K1 Liquid Level Swichgage (15700116)

The EL150K1 Liquid Level Swichgage instrument is a combination liquid level gauge and low limit switch; the instrument includes:

(1) a chamber with pivotal float,
(2) an indicating dial with pointer,
(3) a low level contact.

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.

The primary use of the EL150K1 is for engine cooling systems, surge or expansion tanks, condenser radiator or vapor phase systems, pressurized or atmospheric systems.

The EL150K1 Liquid Level Swichgage instrument can also be used to monitor lube oil, hydraulic fluid or diesel fuel reservoirs and activate alarms and/or shut-down at a predetermined minimum level.

This instrument is built for low pressure systems with a maximum of 25 psi (172 kPa) [1.72 bar].

Features

Snap-Switch: SPDT rated 10 A @ 125 VAC;
0.5 A @ 125 VDC;
10 A 30 VDC.
Die cast aluminum, polyurethane coated case; brass float; polycarbonate lens.
Wire is (3) 18 AWG x 14 in. (1 mm2 x 356 mm).
An explosion-proof model is available.
