L81 Flange Mount Electric

This Model L81 liquid level switch incorporates a slip ring mount configuration and is ideal for applications where a positive process pressure seal is required. It utilizes an explosion proof SPDT or DPDT snap acting dry contact switch and has an extended float rod for installation thru 2" or larger flanges. The design has a non-adjustable trip point and narrow level operation range making it perfect for applications where trip point tampering is unacceptable.
