The LM500 Series automatically monitors and maintains the crankcase oil level of engines, pumps, and compressors, replenishing supply as it is consumed to ensure consistent lubrication. It features a unique, non-clogging thumb valve for a leak-free seal and a three-wire snap-action switch for reliable integration into alarm or shutdown control circuits. The LM500-TF model includes a dedicated test button, allowing operators to verify both float and switch functionality instantly without interrupting equipment operation.
The LM300 Series automatically maintains engine oil levels by replenishing the crankcase as needed, preventing potential equipment failure due to low lubrication. It features integrated switches to trigger alarms or automatic shutdowns if oil levels drop or overfill conditions occur. Designed for rugged industrial use, the series includes CSA-certified explosion-proof models (LM301-EX through LM303-EX) rated for Class I, Division 1 hazardous locations.
The LS200 Series is a high-pressure liquid level switch specifically engineered for harsh gas compressor scrubber applications. Rated for 2000 psi working pressure, it features a 304 stainless steel float capable of operating in fluids with a 0.55 specific gravity or heavier. Housed in a corrosion-resistant nickel-plated body, this Class I, Div 1 certified switch provides reliable alarm or shutdown protection with electric (SPDT/DPDT) or pneumatic output options.
The MLS Series is a float-activated liquid level switch designed specifically for high-pressure gas scrubber applications. It features a clean magnet design that virtually eliminates the accumulation of iron filings and a seal-free construction for long-term reliability. Rated for 2000 psi working pressure and capable of operating in fluids with a 0.50 specific gravity or heavier, this 304 stainless steel switch provides a robust SPDT reed switch output for integration with PLCs or annunciators.
The LR500 Series level regulators are designed to automatically maintain the factory-recommended oil level in lubricators, eliminating the need for manual checks and refills. Each unit features a low-level shutdown switch to protect machinery in the event of oil supply loss. Specifically engineered for Lincoln lubricators, the series includes the LR579 with an adjustable contact and the LR589, which utilizes a hermetically-sealed mercury switch for reliable operation in industrial environments.
The L971 Series is specifically designed to protect Ingersoll-Rand Type 30, Type 40, and ESH compressors by detecting critically low oil levels in the crankcase. Housed in an explosion-proof aluminum enclosure, this switch is UL and CSA listed for Class I hazardous locations. It features a durable SPDT snap-switch and an adjustable float arm that initiates an alarm or immediate shutdown when oil levels fall, ensuring your machinery remains protected from lubrication failure.
