The Murphy Crankcase Level Switch with Stainless Steel Float L971-C detects low oil level in a compressor’s crankcase. As oil level in the crankcase depletes, the float on the L971-C switch falls, and if reaches the predetermined limit, will trip the internal snap-switch which in turn will initiate a shutdown and/or alarm. The L971-C may also be used to detect rising fluid levels in stuffing box containment vessel.
The L971-C is designed for Ingersoll-Rand Type 30, Type 40 and ESH compressors, yet can be adapted to fit other compressors that have an inspection plate extending below normal operating oil level. The L971-C has a 1/2 NPT process connection and features an explosion-proof enclosure, durable SPDT snap-switch and 304 stainless steel float.
