The E-LD400-y Liquid Detection Sensor Rope has a non-conductive polymer mesh covering two sensing wires that lie between the polymer carriers. Fluid has to penetrate the non-conductive mesh in order to close the circuit, which triggers an alert that is reported to the ENVIROMUX Environment Monitoring System. The non-conductive polymer mesh prevents artificial bridges between the sensing wires and false alarms caused by dirt/dust buildup, metal contact or pressure on the rope. Since the mesh covers only the two sensing cables and not the entire rope, the rope dries quickly after being in contact with fluids, minimizing delays between normalcy.
