 Description
The L190S Shielded Liquid Level Switch provides accurate and stable level detection in turbulent, highly-contaminated, non-static liquids. A slosh shield protects the float switch by minimizing effects from tank motion and potential particle interference. The L190S performs in both, oil and water applications. It serves as the perfect solution for level detection in wells, sumps, mobile tanks, filtration systems, and any other application where moving liquid and heavy particles exist.
Principles of Operation
A hermetically-sealed reed switch is actuated by an internal magnet within the float. As the float rises and falls with the liquid level, the magnetic field passes the switch encapsulated within the stem and causes the contact to either open or close.
