Conductivity Level Switches

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

Manufacturer: Omega(USA)

Model: LVCF 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 LVCF switches can accommodate up to five 316 SS fixed rods for 5 different levels of control. The rods are isolated with a PTFE joggle and can be coated with PTFE when the probe is used with aggressive or sticky media that cause buildup. The user can easily modify operating levels in the tank by cutting the length of the electrodes. The LVCF switches are rugged and compact and have no moving parts. This makes them reliable for controlling conductive media as well as for high-pressure applications.

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