Description
ABB UNC4673A HIEE205014R1 Analog Measuring Card
1、 Application in the power industry
Power plant process monitoring
Boiler and turbine monitoring: Accurately collect boiler temperature (0-600 ° C), steam pressure (4-20mA signal), and flow data to achieve superheater protection and efficiency optimization.
Excitation control system: integrated with the UNITOL 6000 system, regulating the excitation current of the generator (with an accuracy of ± 10%) to ensure voltage stability and distribution of reactive power in the power grid.
Transformer monitoring
Real time tracking of oil temperature, winding temperature, and cooling system status, triggering protection actions through DCS (such as Symphony Plus) to prevent overload faults.
2、 Chemical and petrochemical industry
Reactor parameter control
Connect pressure transmitter (0-25MPa) and thermocouple (K-type) to monitor the polymerization reaction process, dynamically adjust the feed flow rate and cooling valve opening.
Pipeline safety monitoring
Detect sudden pressure changes (>threshold alarm) and corrosive medium leakage signals in the conveying pipeline, and link emergency shut-off valves to reduce risks.
3、 Manufacturing automation
Energy Efficiency Management of Production Lines
Collect motor current (0-500A) and voltage fluctuation data, analyze peak energy consumption, optimize equipment start stop sequence, and reduce industrial electricity costs by 15%.
Quality Control System
In the automotive parts spraying line, real-time feedback of coating thickness (μ m level) and drying temperature deviation is provided to ensure process consistency.
4、 Water treatment and environmental protection facilities
Sewage treatment plant
Monitor the dissolved oxygen (0-20mg/L), pH value, and flow rate of the aeration tank, and automatically adjust the aeration machine speed and chemical dosage through PID algorithm.
Water supply network
Remote transmission of pump station outlet pressure and water turbidity data to the central control room to prevent pipe bursts and water quality exceeding standards.
