Gems Sensors & Controls LS3 Float Level Switch

Description:

The GEMS LS3 Float Level Switch is used in liquid level monitoring systems to detect high or low liquid levels in tanks, reservoirs, and process vessels. Commonly installed in water treatment equipment, chemical processing systems, fuel tanks, and industrial fluid handling applications requiring reliable level detection. Maintenance teams, OEM machine builders, and system integrators use this switch for level control, pump automation, alarm systems, and replacement of worn sensing devices.

Applications:

The GEMS LS3 switch is commonly used in sump pumps, condensate systems, coolant reservoirs, chemical tanks, lubrication systems, and water storage applications where automatic liquid level monitoring is required. Its compact design makes it suitable for shallow tanks and restricted installation spaces while the reed switch construction provides long service life and repeatable switching performance in industrial environments.
