    • FW Murphy Liquid Level Switch EL150EX. The EL150EX Liquid Level Switch® instrument is an explosion-proof combination liquid level gauge and low level switch. The instrument includes: (1) a chamber with a rotating float, (2) a dial with pointer, and (3) a low level contact. When properly installed and maintained, the float operates the pointer which in turn both indicates the level during normal operation and closes a switching circuit when the level drops to the low limit set point. The EL150EX has a fixed set point. When properly installed, the unit mounts at your desired liquid level. The set point cannot be tampered with. The primary use of the EL150EX is for engine cooling systems, peak 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 lubricating oil, hydraulic fluid, or diesel fuel reservoirs and to activate and/or deactivate alarms at a predetermined minimum level. This instrument is designed for low pressure systems with a maximum of 25 psi (172 kPa) [1.72 bar]. Snap-in Switch: SPDT rated 10A @ 125 VAC; 0.5A @ 125VDC; 10A 30VDC.
