The L150 Series Level Swichgage® instrument is a combination liquid level gage and low-limit switch; each unit 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. For bigger quantities, please contact us to get a special quote. Technical Data
Murphy LM2000 model maintains the crankcase oil level of an engine, pump or compressor. Adjusted to the correct running-oil-level, the LM2000 will replenish oil as it is used. An integral, low-level switch will alarm and/or shutdown the equipment if supply oil is lost and the equipment continues to use oil. Replaced by FW Murphy LM500 Technical Data
The L129 Series Lube Level Swichgage® instrument is a combination lube level indicating gage and adjustable low and high limit switches. It provides protection against low oil level or high level caused by overfill or fuel or water seepage into the crankcase. Technical Data
Murphy L129CK1 Level Switch The L129 Series Lube Level Swichgage® instrument is a combination lube level indicating gage and adjustable low and high limit switches. It provides protection against low oil level or high level caused by overfill or fuel or water seepage into the crankcase. The L129CK1 was designed for applications requiring a three-wire, above ground electrical circuit. It features ungrounded contacts and a conduit hub to protect electrical wiring. Options are available for both models. Check Lube Level Without Shutting Down. Use On Engines, Pumps, And Compressors. Technical Data
The L971 Level Switch is designed for Ingersoll-Rand Type 30, Type 40 and ESH compressors, yet it can be adapted to fit other compressors that have an inspection plate extending below normal operating oil level. It installs with minimal downtime and has a two-year limited warranty. Durable Low Level Switches. Installs with Minimal Downtime Technical Data
The LM300 Series Level Maintainer automatically adds oil to the crankcase as needed to keep the lube level normal. Most models have built-in switches that will alarm and/or shut down the equipment if the makeup supply is depleted and engine oil level falls or if overfill conditions exist. The LM300 can be used in engines, compressors, pumps and coolers. The LM300 Series EX models (explosion-proof) are CSA certified for Class I, Division 1 Hazardous areas. Technical Data
Murphy DF Level Switch This simple level switch is highly reliable and can be worked into almost any new or existing system without major modification or special tools. DF755 and DF757 are suitable for atmospheric tanks in a non-hazardous area. The SPDT snap-switch for the DF755 is preset for a 4 in. (102 mm) differential in liquid level. The DF757 trip point is adjustable over a 108 in. (2743 mm) differential. Typical application is to start and stop electric driven pump(s) to maintain tank levels. It is also applicable to engine-driven pumps. Technical Data
Murphy LS200 Level Switch Designed for harsh gas compressor scrubber applications, the LS200 Series Liquid Level Switches feature a robust design that trips on rising liquid level only. With both electric and pneumatic models available, the instruments screw directly into the vessel or can be mounted via an external float chamber. The nickel-plated body provides enhanced corrosion protection while the 304 stainless steel float operates in 0.55 specific gravity and heavier fluids. Additional features include: Rated for 2000 psi (13.8 MPa) [138 bar] working pressure Listed for Class I, Div. 1, Grp. C & D locations Canadian registered Stainless steel models available for corrosive atmospheres The LS200 Series replaces the FW Murphy Series L1200 Liquid Level Switches. The MSLS (Scrubber Level System) replaces the LS200 high-level shut-down switch with the MLS-020 magnetic level switch. Technical Data
The FW Murphy LM500 model maintains the crankcase oil level of an engine, pump or compressor. Adjusted to the correct running oil level, the LM500 will replenish oil as it is used. The low level switch will alarm and/or shut down the equipment if the supply oil is lost and the equipment continues to use oil. Direct Mount (DM) capable Eliminates under/overfill due to “human error” See oil level and condition without shutting down Simple installation Automatically maintains lube level Low level, 3-wire, snap-action switch Positive sealing Thumb-Valve™
