Advantages

  • Inside installation
  • High reliability
  • 135 °C maximum liquid temperature
  • Various float and cable types
  • Submersible variant

Description

The operation of the COMECO’s level probe LCSF is based on the switching of a reed switch by a magnetic float, moving alongside a protective tube. Large variety of versions based on different floats is available. The float can be made of stainless steel or plastic; floats with various dimensions and specific gravity are available for use with different liquid density (down to 0.5 g/cm3) and liquid temperature up to 135 °C. Cable wiring is available with various insulations and lengths. The LCSF switch is available in variants designed for inside vessel mounting and in a special submersible variant with additional weight and forced cable insulation.
