Industrial PME-A4 Level Switch

The WOERNER PME-A4 Level Switch is a reservoir- and tank-mounted fluid level detector designed for industrial lubrication and fluid monitoring systems. It provides precise low- and high-level detection for oils, lubricants, coolant, and other industrial fluids, triggering level-switching actions to prevent dry-run conditions and protect pumps, lubrication components, and system reliability. Commonly installed in centralized lubrication systems, hydraulic reservoirs, machine tools, manufacturing equipment, and automated process lines, it supports vertical mounting orientation to simplify integration in cabinets, tanks, and equipment frames. This level switch is designed for compatibility with centralized lubrication and fluid systems and is used to support preventive maintenance, equipment protection, and the replacement of failed fluid monitoring devices by maintenance teams, OEMs, and system integrators alike. With its dependable reservoir and tank level detection, the PME-A4 helps maintain continuous operation, reduce downtime, and ensure steady supply of lubrication and process fluids across industrial environments.
