PLS Series Plastic Level Switches
The Levelpro PLS Series compact level switches combine low cost and reliability with fast, simple
installation. The all plastic level switches contain an hermetically sealed reed switch that is actuated by
magnets that are permanently bonded inside the float. They can be easily adapted to open or close a
circuit based on the rising or falling of the liquid level. The switch action can be reversed by removing the
float, rotating it end-for-end and replacing it on the stem. Vertical models mount internally, oriented within
45° of vertical, or select optional fittings for external mounting. Switch ratings are suitable for many solidstate control systems and small monitors or alarms. Simple relay interfaces can be used for higher
current applications such as pumps and on-off valve actuators

Working Principle
As a direct result of rising or falling liquid a
magnetic field is moved into the proximity
of a reed switch causing its actuation.
