High Temperature Model Extends LS-7 Family of Side-Mounted Liquid Level Switches

Gems Sensors has announced a new high temperature version of the popular LS-7 Series side-mounted liquid level switches for use in small vessels where top or bottom switch mounting is not practical.

Constructed in Versaplast, a material manufactured by Gems, the new models handle temperatures up to +300oF - which is 50% more than other plastic switches in the LS-7 range. Versaplast is compatible with water, oils and chemicals that are suitable for use with nylon. The switches are ideal for high volume use in small tanks including food processing, medical equipment, engine oils and water purifiers.

Competitively priced and durable, the Versaplast LS-7 provides accurate and repeatable switching for high, low or intermediate level sensing. Mounting is through 1/2in NPT ports. The full range of operating temperatures is -40oF to +300oF (-40oC to +148.8oC), with pressures to 100 psi at 70oF.

Operation is straightforward and directly related to movement of a liquid's surface. Depending on the mounting position, as the float rises or lowers with liquid level, a magnetic field is moved into the proximity of a reliable, hermetically sealed reed switch within the housing thereby causing switch actuation. By rotating the switch 180 degrees, the switch operation can be Normally Open or Normally Closed. Arrows on the exterior of the mounting indicate N.O. when pointing up. Units are supplied with 24 in - 26 in lead wires.

Gems offers many other versions within the LS-7 Series, including internally or externally mounted units, and those made of polypropylene or nylon.
