Letop Floatless Relay

Letop floatless relays are level controllers that detect water levels based on the conductivity of the medium measured by using conductive electrodes. When a relay senses the liquid level measured, the output contacts of the relay are energized and latched. These latched outputs are released when the latching electrode is brought out of the medium measured. The operation repeats as the medium’s level change to achieve a continuous level control system.

  • Both general-purpose and panel-use models are available
  • Incorporates an arrester for surge and induced lightning protection
