L971 Crankcase Level Switch

L971 crankcase level switchThe Murphy L971 Series Level Switch detects low oil level in a compressor’s crankcase. As oil level in the crankcase depletes, the float on the L971 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 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.

Features:

  • Durable low level switch
  • Replaces non-explosion-proof switch on Ingersoll-Rand compressors
  • Adaptable to other Compressors
  • Installs with minimal downtime
  • Two year limited warranty
