FW Murphy 15700090 L971 Crankcase Level Switch

Features:

• Durable Low Level Switch
• Replaces Non-Explosion-proof Switch on Ingersoll-Rand Compressors
• Adaptable to Other Compressors
• Installs with Minimal Downtime

The 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 when reaching the predetermined limit, it will trip the internal snap-switch sounding an alarm or initiating shutdown. The L971 is designed for Ingersoll-Rand Type 30, Type 40 and ESH compressors, yet it can be adapted to fit other compressors that have an inspection plate extending below normal operating oil level. The L971 has a 1/2 NPT process connection and features an explosion-proof enclosure, durable SPDT snap-switch and rigid polyurethane foam float.
