LS7 Type 12 – Plastic Horizontally Mounted Level Switch

Gems Sensors introduces several new versions to their LS-7 robust point level switches. These compact, side mount level switches are made from Gems Versaplast™ engineered plastic for high temperature applications up to 300°F (148.9°C).

The Gems Versaplast™ engineered plastic used on these new level switches is an extremely versatile material compatible with a wide range of challenging fluids such as oils and solvents. Versaplast™ enables the new LS-7 Series sensors to provide an affordable solution for handling high temperature applications and corrosive fluids. The durable Versaplast™ LS-7 level switches are CE, UL and CUL approved, are ideal for use within methylene chloride and anti-freeze tanks, and are well suited for low coolant, low hydraulic monitoring within off-highway vehicle and transportation applications.

These new Versaplast™ LS-7 Series versions expand the broad range of small, side mounted level switches from Gems Sensors available for a wide variety of fluids or applications. Additional specifications include pressure capability to 100 psi (6.8 bar), and a float arc of just 1.25 inches – beneficial in confined spaces. Options include internal and externally installed versions, and metric or U.S. threads.

Principle

When the magnetic field of permanent magnet inside the float is moved into to the proximity of the reed switch inside the stationary stem, the reed switch contacts “snap” together and closes the electrical circuit. When the magnetic field is moved away from the reed switch, the reed switch contacts move apart and the circuit is opened.
