KSLL Oil Level Controller

(Two Independent Switches for Low/Low Level Alarm in Explosion Proof Enclosure)

(Formerly Known As Model# 3358)

Operating Principle

KENCO Oil Level Controllers are designed to maintain a running oil level in the crankcase of stationary engines, compressors, and mechanical lubricator boxes. The KENCO Oil Level Controller works in conjunction with an overhead oil supply system which feeds the oil level controller. As the oil is consumed, the oil controller supplies the required amount of oil to maintain a proper level in the crankcase. The oil controller maintains the proper amount of oil in the crankcase by using a float controlled valve.The valve opens and closes as oil is needed in the crankcase to provide a constant oil level. The Kenco KSLL is constructed with two independent switches, one for low level alarm 5/8″ below centerline and another for low level alarm at 7/8″ below centerline. The oil level switches in the KSLL are electric switches in an explosion proof enclosure, rated for hazardous hydrogen gas environments. The float switches monitor the oil in the crankcase. The level within the crankcase directly corresponds with the oil level in the oil level controller housing. If the oil level in the crankcase drops past the designated levels, the switches will trip sending an alarm.
