SWI L500E Series | Custom Multi-Level Float Switches For Large Tanks In Hazardous Locations

Description

The wider displacement L500E Multi-Level Float Switch for Hazardous Locations is designed to monitor up to six levels on a single device. With only a single entry, the L500E can track changing levels within a large tank, as well as monitor liquid interfaces of dissimilar liquids for oil/water separations, chemical emulsions and condensation levels. Probe lengths are available up to 15' with various enclosures, 316 stainless steel floats, and mounting types to suit most applications.

Principles of Operation

The switching action is achieved through the use of an internal magnet within the float assembly and its interaction with the switch mechanism. As the liquid level fluctuates inside the tank, the float moves. Its magnetic field actuates each reed switch inside the stem and completes an electrical circuit.
