ELS-950M Series Rugged Electro-Optic Level Sensor

Brand: Gems Sensors, Inc

The ELS-950M Series represents Gems' most compact alloy-housed electro-optic level sensors. They monitor a broad range of media including OHV type fluids. 

Our UL-approved design features a brass housing, fused glass prism, and TPE insulated wires.

They provide a durable, watertight, and environmentally resistant assembly, ideally suited for use in harsh environments including outdoors and engine bays. They offer excellent temperature and pressure capabilities. 

The ELS-950M is excellent for industrial OEMs requiring a solid-state sensor for small space and high temperature environments.
