Rosemount 1056-02-21-31-AN-UL

Rosemount 1056-02-21-31-AN-UL is a four-wire multi-parameter liquid analytical transmitter manufactured by Emerson Rosemount, supporting dual sensor inputs for continuous water quality monitoring in industrial and municipal water treatment systems. It adopts robust Type 4X polycarbonate enclosure and large customizable display, providing reliable protection against dust, moisture and occasional splash in field installation environments. The liquid analyzer captures real-time analytical signals from multiple water quality sensors, the liquid analyzer supports independent dual-channel measurement simultaneously. Process engineers rely on the liquid analyzer for pH, conductivity, dissolved oxygen and chlorine monitoring. The liquid analyzer features quick start programming and automatic sensor board recognition for fast commissioning.

Rosemount 1056-02-21-31-AN-UL integrates HART digital communication and 4-20mA analog output to transmit measured data to control systems. Its modular hardware design allows field replacement of signal input boards, simplifying configuration changes without removing the whole unit. The water monitoring tracks key water quality parameters for wastewater, boiler water and purified water processes. Precise water monitoring helps operators maintain stable water treatment conditions and meet emission standards. Technicians can perform on-site calibration and diagnostic checks to sustain water monitoring accuracy over long operating cycles. Built-in self-diagnostic functions ensure continuous water monitoring and early warning of sensor faults.

Rosemount 1056-02-21-31-AN-UL is widely applied in power plant water systems, food & beverage production, municipal wastewater treatment and chemical process water loops. Every unit undergoes strict calibration, communication test and environmental aging inspection before shipment. The process measurement design seamlessly connects with DCS and PLC automation platforms. This transmitter delivers dependable process measurement data for closed-loop industrial water control. Convenient menu operation and spare parts support preserve stable process measurement performance for years of continuous service. Global water treatment customers select this model for high-precision, low-maintenance and cost-effective process measurement solutions.
