Conductivity Level Switches

-------------------------------------------------

Manufacturer: Omega(USA)

Model: LVCR Series

Introduction: 

         OMEGA’s conductivity level switches offer a wide range of customized options to meet any application’s needs. They are designed to control the level of all conductive mediums, offering up to 5 different points of level control. Models are available with fixed rigid rods, with removable rigid rods, or with pendular electrodes attached to the housing with cables. These switches suit applications involving both alarm point detection and on/off pump valve control. Installation is easy and operation is maintenance-free.

      The probes work through the variation of the electrical resistance between the reference electrode and the level-control electrode. Conductivity level switches detect the level resistance when their electrodes are covered by the medium.

      An electrically conductive tank wall can be used as the reference electrode. If the tank is made of plastic, concrete, or any other nonconductive material, an additional electrode is required as a reference.

      The LVCR models offer the same features as the LVCF, plus removable 316 SS threaded rods that make it possible to switch the rods. Rods can be ordered separately in longer length and can then be custom cut. Removable rods make the system more versatile, easier to handle, and more forgiving if the rod’s length is cut incorrectly.

      LVCR models are compatible with LVCN-200 Series controllers only.
