LS200 & L1100 Series Liquid Level Switches  
LS200 Liquid Level Switches with 2” NPT mounting are float  
activated to operate an electrical SPDT snap switch (optional  
DPDT on some models) for alarm or shutdown of an engine or  
electric motor. The LS200 connects directly into the vessel wall  
and can be used with a Murphy weld collar (P/N 15050375) or  
Murphy external float chamber (P/N 15700799). L1100  
models (1-1/2” NPT) are also available.  
LS200NDVOR is a float-activated, pneumatic-vent level  
device used to operate dump valves or similar devices.  
The LS200NDVOR provides a 2” NPT mounting with a  
pneumatic output for interfacing with pneumatic devices such  
as our Murphy pneumatic dump valve or with other pneumatic  
instrumentation.  
LS200NDVO is the Dump Valve Operator (DVO) without the  
pressure regulator for those applications where the system  
provides a filter regulator for “instrument quality” air or gas as the control medium.  
LS200N is the pneumatic level switch without the DVO and filter regulator.  
NOTE: Pneumatic media devices require clean, dry, instrument quality air or gas. This unit is  
supplied with a pressure regulator, filter and Murphy 20BPG pressure gage for improved  
system life and trouble-free operation.
