The L129 model is designed for grounded, low voltage electrical systems. There are two models in the L129 Series: L129 and L129CK1. If the float touches the high or low limit contact, a normally open circuit will be completed which can activate alarms and/or shut down the equipment. A 6-3/4 inch (171 mm) deep sight gage allows you to check the condition and level of your oil without shutting down the equipment.įingertip adjustable limit contacts, through 4-7/8 inch (122 mm) range, make it simple to set high and low limit contacts. It provides protection against low oil level or high level caused by overfill or fuel or water seepage into the crankcase.

The L129 Series Lube Level Swichgage instrument is a combination lube level indicating gage and adjustable low and high limit switches. Installation Instructions: OPLH/OPLHACS Series OPLHC and OPLHACS series are available in indication only MurphyGage models (OPLHAGS). OPLHBP/OPLHABPS Internal latching control relays are available to provide ON/OFF automation for electric motor applications. Models are available with a rugged bourdon tube or a 316 stainless steel bellows sensing element for greater accuracy and sensitivity in lower ranges. Contacts have self-cleaning motion to enhance electrical continuity. OPLHC/OPLHACS Series Swichgage instruments include two adjustable, pilot duty, pointer type contacts. Specialized models are available for specific applications involving engines or electric motors.

Adjustable limit switches are accessible from the front of the Swichgage instrument. Surface-mount or panel-mount enclosures are available for both model series. Limit switches can be wired directly to electric pilot circuits to operate alarms, shut down or start/stop pumps to maintain predetermined levels. The OPLHC/OPLHACS Series Level Swichgage instruments are combination level-indicating gages with adjustable low- and high-limit switches. Installation & Operations Manual: LS200 Series

Stainless steel models available for corrosive atmospheres.

The MSLS (Scrubber Level System) replaces the LS200 high-level shut-down switch with the MLS-020 magnetic level switch. The LS200 Series replaces the Murphy Series L1200 Liquid Level Switches. The nickel-plated body provides enhanced corrosion protection while the 304 stainless steel float operates in 0.55 specific gravity and heavier fluids. With both electric and pneumatic models available, the instruments screw directly into the vessel or can be mounted via an external float chamber. Installation & Operations Manual: MLS Seriesĭesigned for harsh gas compressor scrubber applications, the LS200 Series Liquid Level Switches feature a robust design that trips on rising liquid level only.

All models screw directly into the scrubber or can be mounted via an FW Murphy External Float Chamber.

Trip on rising and falling without need to rotate body.

Rated for 2000 psi (13.8 MPa) working pressure.

304 cast equivalent SS body and 304 SS float.

Designed for harsh gas compressor scrubber applications.

Operates in 0.50 specific gravity or heavier fluids.

ANSI/ISA 12.27.01 compliant (Single Seal).

Clean magnet design virtually eliminates iron filing accumulation on the magnet.

The test button tests for float function the complete mechanism including the magnetic activation of the reed switch and the wiring from the switch to the control panel.

NPT models and with or without the test button. The MLS Series is available in both 1 1/2 and 2 in. The MLS connects directly into the gas scrubber wall and can be used with an FW Murphy weld collar or FW Murphy external float chamber.

MLS Series Liquid Level Switches are float activated to operate an electrical SPDT reed switch for annunciation/ pilot signal for indication of high level to an annunciator, controller or PLC. Sales Bulletin: Scrubber Level Control System

Hex Union Allows Plug and Seat Replacement Without Piping Removal Operates on 30–70 psi (207–483 kPa) Control Pressure Manual Valve Operator.

LS200, MLS-020 High Level Shutdown Switchĭesigned for Harsh Gas Compressor Scrubber Applications Stainless Steel Float: Specific gravity varies by model and configuration For Separators/Scrubbers rated for up to 2000 psi (13.8 MPa) Working Pressure Electric and Pneumatic Models Available.

You save money by purchasing the SLS system which includes the following: Wetted metal parts are made to survive constant use in corrosive environments. The system provides for liquid control in gas scrubber applications by dumping liquids to drain and protect compressors with with high liquid level switch.
