• Steam Turbine/Generator Rotational Speed Monitoring
  Used for shaft rotational speed detection of steam turbines or hydro-generators in thermal power plants and nuclear power plants, to monitor the rotor operation speed in real time, ensuring the generator set operates stably at the rated speed. When the speed is abnormal (such as overspeed or speed fluctuation), the module can promptly output signals to trigger the protection mechanism, preventing mechanical damage or shutdown accidents caused by speed loss.
• Fan/Pump Equipment Condition Monitoring
  Monitors the rotational speed of rotating equipment such as induced draft fans and feed water pumps, and evaluates the equipment operation status by combining parameters such as vibration and temperature. For example, when the fan speed is abnormal, potential faults such as bearing wear and impeller imbalance can be detected in advance, providing data support for preventive maintenance and reducing unplanned downtime.

• Compressor Rotational Speed Control
  Applied to key equipment such as natural gas compressors and centrifugal compressors, it accurately monitors the rotor speed to ensure stable compression ratio and avoid surge phenomena caused by speed fluctuations. Meanwhile, it collaborates with the DCS system to achieve closed-loop speed control, optimize process parameters, and improve production efficiency.
• Pump Equipment Speed Regulation
  In equipment such as oil transport pumps and reactor agitator pumps, real-time speed detection is combined with frequency converters to achieve stepless speed regulation, meeting the flow requirements of different process stages. For example, during chemical material transportation, the pump speed is automatically adjusted according to pipeline pressure to ensure transportation efficiency and system safety.

• Rolling Mill Main Drive System Monitoring
  In steel rolling production lines, it performs high-precision monitoring of the rotational speed of rolling mill main motors and reducers to ensure the matching of roll linear speeds, avoiding steel plate thickness deviations or rolling defects caused by inconsistent speeds. It can also collaborate  with the tension control system to improve rolling accuracy and product quality.
• Blast Furnace Fan Speed Monitoring
  Monitors the rotational speed of fans in the blast furnace blowing system in real time to ensure stable blowing pressure and flow of the blast furnace. When the fan speed is abnormal, it promptly alarms and switches to a standby fan in  collaboration, preventing fluctuations in blast furnace conditions from affecting hot metal quality.
