NC - Mechanical Float Level Switches
All level switches use a hermetically sealed reed contact actuated by a magnet in the float. As the float rises and falls, the magnetic field causes the switch inside the stem to open or close. Our level switches can be mounted in the tank top or bottom, or can be adapted for side mounting. Switches will operate normally with up to a 30 degree tilt from vertical.
All single point switches are field selectable for normally open (N/O) or normally closed (N/C) switch operation by simply removing the retaining ring and flipping the float.
Some level switches can be provided to detect the interface between two dissimilar liquids such as water and oil. Our level switches can be provided with other mounting styles such as flanges, bent stem, different NPT, straight threads, and metric size mounting plugs.
Our level switches can be made intrinsically safe for hazardous applications by the use of I.S. barriers such as the REL-6000 series. Contact protection relays such as the RL-series should always be considered to protect switches from overload.
