L971 – An explosion-proof crankcase level switch

L971 Crankcase Level Switch
The 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
