FLUID LEVEL
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
