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 or Murphy external float chamber. L1100 models 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.
