LS-3 Slosh Shield/Bottle/Low Level Switch
Brand: Gems Sensors, Inc
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.
- Slosh Shield: Compact, all-polypropylene switch with slosh shield is ideal for use with turbulent liquids in small tanks. FDA approved materials
- Bottle Level: For external mounting on tanks too small to accommodate internally mounted switches. (See note below)
- Low Level: For detecting levels as low as 5/8" (16 mm) from tank bottom. Use in water, gasoline, some oils and chemicals
