Murphy EL150K1液位開關 15700116
EL150K1 Liquid Level Swichgage 15700116

EL150K1液位監測儀是液位計和低限位開關的組合;該儀器包括：

（1）一個帶樞軸浮子的腔室，
（2）一個帶指針的指示刻度盤，
（3）一個低電平觸點。

正確安裝和維護后，浮子操作指針，而指針又在正常運行期間指示電平，并在電平降至下限設定點時關閉開關電路。EL150K1的主要用途是發動機冷卻系統、喘振或膨脹水箱、冷凝器散熱器或氣相系統、加壓或大氣系統。EL150K1液位監測儀還可用于監測潤滑油、液壓油或柴油油箱，并在預定的最低液位啟動警報和/或關閉。

該儀器專為最大壓力為 25 psi （172 kPa） [1.72 bar] 的低壓系統而設計。

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.
