The LS200 Liquid Level Switch with 2" NPT mounting is float activated to operate an electrical SPDT snap switch for alarm or shutdown of an engine or electric motor. The LS200 connects directly into the vessel wall and can be used with a weld collar (Murphy Part# 15050375) or Murphy external float chamber. The LS200 is designed for harsh gas compressor scrubber applications. The improved design provides better snap action and dependability with a reduced number of moving parts. A nickel plated body provides enhanced corrosion protection, and the 304 stainless steel float operates in 0.5 specific gravity and heavier fluids. The LS200 is rated for 2000 psi (13.8 MPa) [138 bar] working pressure and listed for Class I, Division I, Group C & D locations.
