The Murphy Oil Level Regulator with Low-Level Shutdown Contact Switch LR589NC automatically adds oil to a lubricator to maintain the factory recommended level. This function eliminates the work time necessary for manual checks and refills. This model is designed for Lincoln Lubricators and it features an adjustable low-level shutdown contact. If the lubricator oil level drops below the minimum operations level, the low-level switch will operate an alarm and/or shutdown the equipment.

The LR589NC is the normally closed wired version of the LR589.
