Murphy EL150EX防爆液位开关 15700121
EL150EX: Liquid Level Swichgage And Low Limit Switch; Explosion Proof 15700121
EL150EX：液位开关和低限位开关;防爆 （15700121）
EL150EX液位计是一种防爆组合液位计和低限位开关。
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，
以及（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。EL150EX具有固定的设定点。正确安装后，设备将安装在您所需的液位。设定点不能被篡改。该EL150EX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。EL150EX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/或停机。
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。微动开关：SPDT 额定值 10 A @ 125 VAC;0.5 安 @ 125 伏直流电;10 A 30 伏直流电。砂铸铝机身，喷漆外壳;304不锈钢浮子;钢化玻璃镜片。接线端子的电线。CSA 列名危险场所 I 类，I 类，C 组和 D 组。

EL150EX Liquid Level Swichgage (15700121)
EL150EX: Liquid Level Swichgage And Low Limit Switch; Explosion Proof (15700121)
The EL150EX Liquid Level Swichgage instrument is an explosion proof combination liquid level gauge and low limit switch.
The instrument includes:
(1) a chamber with pivotal float,
(2) an indicating dial with pointer, and
(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 EL150EX features a fixed set point. When properly installed, the unit is mounted at your required liquid level. The set point cannot be tampered with.
The primary use of the EL150EX is for engine cooling systems, surge or expansion tanks, condenser radiator or vapor phase systems, pressurized or atmospheric systems.
The EL150EX Liquid Level Swichgage instrument can also be used to monitor lube oil, hydraulic fluid or diesel fuel reservoirs and activate alarms and/or shutdown at a predetermined minimum level.
This instrument is built for low pressure systems with a maximum of 25 psi (172 kPa) [1.72 bar]. Snap-Switch: SPDT rated 10 A @ 125 VAC; 0.5 A @ 125 VDC; 10 A 30 VDC. Sand cast aluminum body, painted case; 304 stainless steel float; tempered glass lens. Wires to the terminal block. CSA Listed for Hazardous Locations Class I, Division I, Groups C & D.
