Dwyer Instruments L6EPB-B-S-3-C Switch

The Dwyer Instruments L6EPB-B-S-3-C is a rugged, magnetically actuated liquid level switch designed for heavy-duty process control. Built with a brass upper housing and a matching brass lower housing machined from solid bar stock, this unit ensures leak-proof performance in demanding environments. It features a 304 stainless steel spherical float and a brass external float chamber, providing superior durability compared to standard plastic alternatives. The SPDT switch mechanism operates without a mechanical linkage, utilizing a magnetic coupling that reduces wear and maintenance requirements. This model supports a 1 inch line size with NPT connections and is specifically engineered for horizontal mounting. With its weatherproof and explosion-proof enclosure rating, it is suitable for Class I, Groups A, B, C, and D, making it a reliable choice for monitoring oil-water separators, chemical processing tanks, and industrial refineries where hazardous vapors may be present.

• Magnetic Actuation: Eliminates mechanical linkage failures, ensuring high reliability in critical level-sensing applications.
• Explosion-Proof Enclosure: Rated for hazardous locations (Class I, Groups A-D; Class II, Groups E-G) to maintain site safety standards.
• Robust Wetted Materials: Combines a 304 stainless steel float with a brass body for compatibility with a wide range of non-corrosive liquids.
• Maintenance-Friendly Design: The electrical assembly can be serviced or replaced without removing the housing from the process line, preventing costly downtime.
• High Pressure Capability: Engineered to withstand process pressures up to 350 psig (24.1 bar).

What is the minimum specific gravity required for the L6EPB-B-S-3-C?
This model requires a minimum liquid specific gravity of 0.7 for consistent float buoyancy and switch actuation.

Can this float switch be installed vertically?
No, the L6 series is designed specifically for horizontal mounting. Proper orientation requires the index arrow on the side of the housing to point downward.

Is the switch assembly field-replaceable?
Yes, one of the primary advantages for contractors is that the internal switch mechanism can be replaced without disturbing the process piping or vessel connections.
