The Gems LS-1900TFE level switch is designed for applications in which all-plastic material is desirable and tank space is not restricted. Featuring Teflon construction, the LS-1900TFE resists build-up of foreign material or sticky media. This ensures float travel remains uninhibited in viscous or corrosive liquids.

The LS-1900TFE is rated for temperatures from -40 to 300°F and pressures to 30 PSI. It is equipped with an SPDT switch which is selectable N.O. or N.C. by inverting the float on the unit stem. The LS-1900TFE uses a 1/4" NPT process connection and 24" Teflon jacketed lead wires.
