ELE-802 transmitters measure liquid level from hydrostatic pressure. The stainless steel probes are immersed directly in the liquid and provide an electrical signal for a monitoring or control system. Applications include storage and fire-water tanks, wells, reservoirs, municipal water systems, irrigation and compatible wastewater processes.

Match the liquid to the wetted materials, then choose the measuring range, output and cable length. Keep the model-specific overload and temperature ratings with the selected variant. ELE-802E addresses particle-related clogging; ELE-802L adds electrical surge protection; ELE-802T provides the stated RS485 configuration. Choose a compatible external indicator when local numerical or bar-graph display is required.
