Oil Level Controllers and Switches

Oil Level Controllers and Switches Descriptions

Oil Level Controllers and Switches from Kenco Engineering are designed to maintain the running oil level in the crankcase of stationary engines, compressors, and mechanical lubricator boxes.

The Kenco oil controller works in conjunction with an overhead oil supply system that feeds the oil level controller. As the oil is consumed, the oil controller supplies the required oil. The oil controller controls the amount of oil in the crankcase with a float-controlled valve. The valve opens and closes as oil is needed in the crankcase to provide a constant oil level.

Operating Principle For Oil Level Controllers

Oil level switches are designed as a safety devices for the stationary engine or compressor. The oil level switch monitors the oil level in the crankcase. The level within the crankcase directly corresponds with the oil level in the oil level switch housing. The engine or compressor constantly consumes the oil from the crankcase. If the oil level in the crankcase drops past the designated level, the switch will trip and trigger an alarm. Depending on which configuration you have, the switch will trip for high/low-level conditions.

Model Specifications

Model K512 Oil Level Controller

The Kenco K512 utilizes the operating principles of both the oil level controller and the electric switch. The case-to-ground switch and the circuit will remain open until the oil level drops 1/2” below the centerline of the sight window. The K512 is for non-hazardous locations and locations where space is limited.
