ELS-1150 Series Single Point Electro-Optic Level Sensor

The ELS-1150 Electro-Optic Level Switch delivers dependable point-level detection for data center liquid cooling systems, including CDUs, expansion tanks, and auxiliary coolant loops. Its solid-state sensing design has no moving parts, enabling maintenance-free operation in always-on environments. A fused-glass prism eliminates leak paths and supports pressures up to 2,500 psi, while compatibility with water-glycol mixtures, dielectric fluids, and specialty coolants supports a range of direct-to-chip and hybrid cooling architectures. The compact ELS-1150 provides reliable level alarms to help protect pumps, heat exchangers, and IT hardware from coolant loss or air ingestion.
