LS200

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 via a thread-o-let directly into the vessel wall and can be used with a weld collar (P/N 15050375) or Murphy external float chamber. L1100 models (1-1/2” NPT) are also available.

LS200NDVOR

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 snap action output for interfacing with pneumatic devices such as our Murphy pneumatic dump valve or with other pneumatic instrumentation.

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.
