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
