Gems Sensors & Electronics FLS-7 Fiber Optic Level Switch

The Gems Sensors & Electronics FLS-7 Fiber Optic Level Switch is a fiber optic level sensing device that detects liquid presence at a defined point and outputs a switch signal when the sensing point is reached. It is designed for use in tanks and vessels where electrical isolation from the process is important, because the sensing element is optically coupled and the switch output is isolated from the process media. The optical sensing approach helps minimize corrosion risk and allows level monitoring without a direct electrical path into the liquid. It integrates with standard control circuits via its isolated switch output, enabling straightforward connection to PLCs or controllers. As part of Gems' fiber optic level switch family, the FLS-7 provides a compact, robust option for dependable level detection in challenging process environments.
