Technical details and application highlights

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

The LM1, LM2, and LMM1 stainless steel float level switches are engineered for precise and reliable liquid level monitoring in industrial environments. Designed for tanks, reservoirs, and process systems, these switches offer superior durability and performance. With AISI 316 stainless steel construction, they are ideal for corrosive liquids, aggressive chemicals, and demanding operating conditions.

Key Features

  • Robust stainless steel AISI 316 body, float, and mounting
  • Multiple actuation configurations (NC, NO, SPDT)
  • High resistance to corrosion and pressure
  • Suitable for water, oil, and chemical applications
  • Certified for industrial and marine environments

Design & Functionality

The float level switch operates using a magnetic float mechanism that activates internal contacts when liquid levels change. This ensures accurate switching and consistent performance. The LM1 offers a single actuation point with NC/NO contact, LM2 provides SPDT switching, and LMM1 supports dual actuation points for enhanced control.

Total Crossed Beams

The internal switching mechanism ensures precise activation points, allowing consistent detection of liquid levels across various tank sizes and fluid types. This improves reliability in automated systems and reduces operational risks.

Beam Pitch Options

Customizable mounting options including flange (Ø 92) and threaded G2” connection provide flexibility for installation across different tank configurations. This adaptability ensures seamless integration into existing industrial setups.

Intrinsic Synchronism

The design ensures synchronized switching action, reducing signal errors and improving system accuracy. This makes it ideal for critical applications where precise level control is essential.

Operational Advantages

These float switches offer long-term reliability with minimal maintenance. Their high pressure tolerance (up to 10 bar) and temperature resistance (-10°C to +80°C) make them suitable for harsh industrial environments. With IP65 protection and certified performance, they are widely used in manufacturing, marine, and process industries for efficient liquid level control.
