Gems Sensors & Controls Single-Point Level Switches LS-3 Series

• Slosh Shield
• Bottle Level
• Low Level

The durable construction of these reed switch designs ensures long, trouble-free service. Because the effects of shock, wear and vibration are minimized, these hermetically sealed switches provide precise repeatability with no more than 1% deviation. The switch actuation points remain constant over the life of the unit.

Gems™ level switches operate on a direct, simple principle. In most models, a float encircling a stationary stem is equipped with powerful, permanent magnets. As the float rises or lowers with liquid level, the magnetic field generated from within the float actuates a hermetically sealed, magnetic reed switch mounted within the stem. The stem is made of non-magnetic metals or rugged, engineered plastics.

• P/N 142545 - with Slosh Shield: Compact, all-polypropylene switch with slosh shield is ideal for use with turbulent liquids in small tanks. FDA approved materials.
• P/N 46999 - Bottle Level: For external mounting on tanks too small to accommodate internally mounted switches. (See note below)
• P/N 76707 - For Low Level: For detecting levels as low as 5/8" (16 mm) from tank bottom. Use in water, gasoline, some oils and chemicals

• Engineered Plastics
• Ideal for Shallow Tanks
• Low Cost/High Volume Use

The durable construction of these reed switch designs ensures long, trouble-free service. Because the effects of shock, wear and vibration are minimized, these hermetically sealed switches provide precise repeatability with no more than 1% deviation. The switch actuation points remain constant over the life of the unit.

Ideal for shallow tanks or restricted spaces, or for any low-cost, high volume use. LS-3 Series are available in FDA/NSF compliant materials upon request, consult Gems™ for details.
