SBEM’s Magnetic Float Switch (Side Mounted) Series 137-EAEY is a robust level measurement solution, designed for reliable and precise level control in industrial tanks and vessels across global markets. Operating on a magnetic repulsion principle, the float movement activates switch elements through a non-magnetic wall, ensuring leak-proof performance and long-term durability without material fatigue. Its modular design includes switch, flange, and float modules, offering customized configurations for electric ON/OFF or pneumatic proportional outputs. Available with flameproof enclosures, adjustable or fixed differential settings, and high-temperature stand-offs, this switch meets IP67 protection standards. All wetted parts are crafted from corrosion-resistant stainless steel (AISI 316), and multiple float chamber types are available to suit horizontal or external mounting. With contact ratings up to 10A @ 230VAC and options for both standard and ANSI slip-on flanges, Series 137-EAEY is ideal for process industries such as oil & gas, chemicals, and power. This ensures SBEM remains a trusted name in level measurement worldwide.
