Technical details and application highlights

Review the complete description, feature set, and specification details before sending your inquiry.

The LMD and LM low-cost level switches are engineered to provide dependable liquid level monitoring in industrial environments. Designed for efficiency and affordability, these float-based level switches offer consistent performance across a wide range of fluid control applications. Industries requiring compact, reliable, and cost-effective level detection solutions benefit from their robust construction and precise switching capability.

Key Features

These level switches are built with high-quality brass materials, ensuring corrosion resistance and durability in demanding environments. The NBR float enhances reliability when working with various liquids, while the SPDT contact configuration supports flexible switching operations. Their compact design makes them suitable for installations where space is limited without compromising functionality.

Design & Functionality

The LMD and LM switches operate using a float mechanism that responds to fluid level changes. As the liquid rises or falls, the float activates the internal switch, enabling accurate control of pumps, alarms, or automated systems. The design ensures minimal maintenance and consistent performance over extended usage.

Total Crossed Beams

Although not based on optical beams, the switching mechanism ensures precise actuation at a defined level point, offering reliable response for industrial processes requiring accurate level detection.

Beam Pitch Options

The device offers a single actuation point, simplifying installation and ensuring predictable operation for applications that require straightforward level monitoring.

Intrinsic Synchronism

The internal switching system maintains synchronized operation with fluid movement, reducing false triggering and ensuring stable performance even in dynamic fluid conditions.

Operational Advantages

These low-cost level switches provide significant advantages, including ease of installation, minimal maintenance, and high durability. With a temperature tolerance from -10°C to +80°C and pressure resistance up to 10 bar, they are suitable for various industrial fluids. Their compact size and reliable switching make them ideal for tanks, reservoirs, hydraulic systems, and fluid automation processes.
