Description

LC20 is a low-cost electronic level controller/indicator for rail mounting. Through its relay output, this device directly controls electrical pumps, valves, etc. and may be used either for tank emptying (drainage) or tank filling (supply). Two versions are available employing different methods for level measurement:

• LC20 with resistive input., i.e. measuring electrical conductivity of the liquid between electrodes or between electrode and metal tank body, applicable for liquids with relatively high conductivity that are normally used in chemical, paper, food, wine, biotechnological industries, etc;
• LC20 with contact input, accepting signals from contact level switches (float, optical, etc.), applicable for various non-conductive liquids or cases of heavy condensation, vaporization, or foaming, such as in heating and water supply installations, etc.

An optional output activation threshold adjustment via potentiometer on the front panel provides better adaptation to liquids with different conductivity for both versions.
