Installs with Minimal Downtime
Available on backorder
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 has a 1/2 NPT process connection and features an explosion-proof enclosure, durable SPDT snap-switch and rigid polyurethane foam float. A 304 stainless steel float is available on certain configurations.
Operating Temperature Range: -15 to 275°F (-26 to 135°C)
