The LM1, LM2, and LMM1 CTA–GTA explosion-proof level switches are advanced industrial solutions designed for accurate liquid level detection in hazardous environments. Built to meet ATEX standards, these level switches are ideal for industries such as oil & gas, petrochemical, chemical processing, and industrial manufacturing where safety and reliability are critical. With robust brass construction and precision float technology, they provide dependable performance in explosive atmospheres.
Key Features
These explosion-proof level switches offer multiple actuation configurations, including single and dual switching points. The LM1 and LMM1 models support high switching capacity, while the LM2 provides SPDT contact functionality for versatile control systems. Designed for durability, the switches operate efficiently under varying pressure and temperature conditions.
Design & Functionality
The devices are engineered with a compact yet rugged design, featuring brass body and mounting components for corrosion resistance and long service life. The NBR float ensures stable buoyancy and accurate level detection even in viscous fluids. The CTA and GTA mounting options allow flexible installation across different tank sizes and industrial setups.
Total Crossed Beams
The internal switching mechanism ensures precise actuation points with minimal deviation. This guarantees accurate level detection, reducing the risk of overflow or dry running in industrial systems.
Beam Pitch Options
Available in multiple configurations, these level switches support customized installation lengths up to 1500 mm (CTA) and 2500 mm (GTA). This flexibility ensures compatibility with a wide range of tank geometries and process requirements.
Intrinsic Synchronism
The switches are designed with intrinsic safety parameters, ensuring reliable operation in explosive gas environments. The ATEX II 1 G Ex ia IIC T6 certification guarantees compliance with strict safety standards.
Operational Advantages
These level switches provide consistent performance with low maintenance requirements. Their high switching accuracy, resistance to harsh environments, and robust electrical capacity make them suitable for demanding industrial applications. With stable operation across varying fluid densities and viscosities, they enhance process efficiency and safety in hazardous locations.
