Murphy Level Switch L129

This 6-3/4 inch (171 mm) deep sight gauge lets you monitor oil level and condition without stopping the equipment.With fingertip-adjustable limit contacts over a 4-7/8 inch (122 mm) range, setting high and low limits is easy. When the float reaches a limit, a normally open circuit is completed, which can trigger alarms or shut down the equipment.The L129 Series includes two models: the L129 and L129CK1. The L129 is designed for grounded, low-voltage systems with a single wire-to-ground circuit, while the L129CK1 is suited for applications needing a three-wire, ungrounded circuit with a conduit hub to protect wiring. Both models have optional features available.Proper installation and maintenance allow the L129 Series Lube Level Swichgage to effectively monitor and protect engines and pumps from lubrication issues that could cause severe damage.This series is recommended for engines and pumps with larger crankcase capacities.
