Technical details and application highlights

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

The LM1, LM2, and LMM1 level switches with stop ring are engineered for accurate and dependable liquid level monitoring across industrial environments. Designed to meet the demands of automation systems, fluid control units, and process industries, these switches provide consistent performance in tanks, reservoirs, and hydraulic systems. Their robust construction and flexible configurations make them suitable for a wide range of industrial applications requiring precise level detection.

Key Features

These level switches feature high-quality brass bodies combined with NBR floats, ensuring resistance to wear and compatibility with various fluids. The anodized aluminium mounting enhances durability and corrosion resistance, making them ideal for harsh industrial environments. With multiple actuation configurations, including NC/NO and SPDT contacts, users can select the most suitable switching mechanism for their application.

Design & Functionality

The LM series is designed with a stop ring mechanism that ensures accurate positioning and reliable actuation points. This enhances operational precision while reducing mechanical wear. The compact yet robust design allows easy installation in vertical configurations, ensuring stable and repeatable performance.

Total Crossed Beams

The internal switching mechanism is optimized to deliver stable electrical performance under varying load conditions. This ensures smooth operation in automated systems and prevents signal inconsistencies during liquid level changes.

Beam Pitch Options

The availability of single and dual actuation points allows flexibility in monitoring multiple liquid levels within a system. This makes the LM1 suitable for basic applications, while LMM1 supports more complex level control requirements.

Intrinsic Synchronism

The float movement and switching mechanism are precisely synchronized to ensure accurate response to liquid level variations. This intrinsic synchronization enhances reliability in dynamic industrial environments.

Operational Advantages

These level switches offer excellent resistance to pressure, temperature, and fluid viscosity variations. With easy installation options such as threaded and flange mounting, they are adaptable to various industrial setups. Their long operational life and minimal maintenance requirements make them a cost-effective solution for industries seeking dependable liquid level control.
